Huawei terminals attended the China Mobile Global Partner Conference, and all the new products in the whole scene were exhibited.

    From October 11th to 13th, 2023, the 2023 China Mobile Global Partner Conference and the 11th China Mobile Global Partner Conference were held in Guangzhou Poly World Trade Expo, China. During the exhibition, Huawei terminals brought a variety of products to participate in the exhibition, allowing participants to deeply experience the latest products of Huawei terminals.

    Recently, Huawei Terminal has released the new M7 and Mate60 series in three key areas, namely, new energy vehicles, mobile phones and full-scene smart life, which has boosted the rapid development of the industry.

    At this exhibition, Huawei Terminal brought flagship new products, sports health, government-enterprise solutions, smart home and new M7 in the world to the exhibition. The site is divided into five sections: 1+8 exhibition area, sports health, smart home, terminal government and enterprise, and the new M7 test drive. Huawei also won two awards from China Mobile, the Best Terminal Partner Award and the Most Popular Product Award.

    Mate60 series single ride

    According to the supply chain news, as of the end of September, the sales of Huawei Mate 60 Pro and Mate 60 have exceeded 1.1 million units. At present, the industry is optimistic about the future performance of Mate series.

    The impact of Huawei terminals on the industry lies not only in the market, but also in the continuous sales of Huawei Mate60 series, which has a greater impact on the domestic supply chain. Enterprises such as optics, panels and structural parts are accelerating production to meet the market demand of Huawei Mate60 series.

    Huawei Terminal and China Mobile have always maintained close cooperation, with a high degree of cooperation in the fields of mobile phones, wearables, routers and other products, consumers and businesses, as well as number card business and consumer stickiness. This time, Huawei’s terminal exhibition area also has a terminal government and enterprise area for the live audience to experience, and continue to empower the industry in the field of secure instant messaging with partners.

    Ask the new M7 to turn the tide.

    As the star SKU of Huawei’s smart car selection, Wenjie New M7 has recently ushered in an upgrade and change. After listing, it has become the top stream in the recent auto market with its excellent product strength. The data shows that since its release on September 12th, the cumulative quantity of the new M7 has exceeded 50,000 vehicles.

    Huawei’s smart car selection, especially the series of cars in the world, has experienced a low period, which is basically in line with the current situation of the domestic new energy vehicle market. Often, the technical upgrade of new models is obvious, and then they set sail in a high profile at the initial stage of listing. However, due to the rapid technical upgrade of the industry, as more brands of new products come out one after another, the result will be a rapid suppression of old models, which will lead to the weakness of the latter, and the impact will be to force major brands to continue to invest heavily to ensure the technological leadership of new cars.

    The upgrade of the product strength of the new M7 in the world and the "increasing the quantity without increasing the price" brought by the high cost performance are also the main reasons for detonating the market. At the conference site, Huawei Terminal also set up a new M7 test drive exhibition area for customers with test drive needs to test drive. It is reported that Huawei’s deeply empowered products, such as M9 and S7, will also be available.

   Full scene, new products landing, efficient ecological experience

    This time, Huawei Terminal also moved almost all the new products from the autumn full-scene conference to the exhibition site, so the audience can experience the new products of Huawei Terminal in the first time. Huawei terminals have always had a clear category positioning for each business line, and at the same time, they have also planned more carefully in ecological positioning, further consolidating the ecological moat.

    Huawei MatePad Pro 13.2 inches has a stronger office atmosphere. The new PC-level WPS Office, combined with HarmonyOS intelligent interaction, brings a better PC-level office experience, and realizes the document synchronization between PC and mobile phone for the first time; Huawei WATCH ULTIMATE DESIGN Extraordinary Master Smart Watch is Huawei’s new interpretation of luxury industrial products. As Huawei’s first gold smart watch, this product has made another breakthrough in material technology, blending 18K precious gold for the first time; Huawei FreeBuds Pro 3 TWS headphones use the star flash technology, which improves the physical bandwidth by 4 times and the anti-interference ability by 2 times. Based on the new L2HC 3.0 protocol, it can realize lossless transmission of 1.5Mbps audio and bring lossless sound quality with super CD quality.

    Huawei’s terminal’s understanding of new products in the whole scene, while fully putting cutting-edge innovative technologies into product strength, brings a unique ecological wisdom interactive experience according to category positioning. Under the "1+8+N" system, the central position of the mobile phone is defined, and with the intelligent interaction of HarmonyOS, a number of core technologies are used as the starting point to expand and explore more functions. Huawei terminals have successfully built their own ecological moat.

Inventory of mainstream film marketing companies (II): Dark Horse Taoxiu is backed by the platform, and it rises rapidly from four to four.

author/Adasi

# Huang Xuan quarrels with Yang Zishan #, # Guan Xiaotong’s father gives Amway white wine to foreign actors #, # Chaoneng’s family has no normal people # ……

When you open Tik Tok, you can always see hot search topics as short as those in parents’ homes. Clicking on them is actually a movie marketing clip. Unconsciously, the deep combination of traditional marketing and content has been immersed into our lives.

Last week, I gave you an inventory of some mainstream film marketing companies (portal "Inventory of Mainstream Film Marketing Companies (I)"). After several rounds of shuffling, some established marketing companies gradually withdrew from the market. At present, either the film and television companies have strong marketing teams, such as Light, Bona, Huayi, etc., or they are attached to capital and platforms. For example, Dark Horse Marketing won Ali’s investment, and immediately film and television was acquired by Confucianism and Italy Film and Television.

Not only the big waves wash sand, but also the fiery short video outlets make short video marketing companies stand on the forefront. A number of emerging companies, such as Beita Culture, Cycling, and Four Four Get Eight, appear in the film marketing team.

Road painting film and television:

Pay attention to the introduction of foreign films and cross-industry cooperation

A few years ago, because of participating in the promotion of Hollywood blockbusters such as Fast and Furious 8, Wolverine 3 and Transformers 5 in China, giving way to painting film and television has established a reputation in the field of film and television industry and brand marketing.

Foreign films help to promote, and the cross-industry cooperation between films and brands is the strong point of road painting film and television. In the early years, I participated in the co-production of Hollywood blockbusters, from the introduction of the Japanese film "Thieves Family" in 2018 to the Japanese niche fantasy love animation "Hello World" this year. The box office broke through 100 million, and there were all road paintings behind it.

The Spring Festival stalls contributed to the cross-border linkage between A Writer’s Odyssey and Audi, which is also a recent successful case of Road Painting.

Road painting film and television also entered the online movie this year, and was responsible for the exclusive announcement of the action film "The Sneak Action of Drug Hunting" at the end of October.

Like a duck to water:

Work closely with Bona

Rudushui Film & Television is a case marketing company established in 2014. From the projects handled by the company, it can be seen that Rudushui has a close relationship with Bona Film, the producer, whether in the early days of "Taking the Tiger Mountain Outward" or "operation mekong" or in Chinese Doctors and The Battle at Lake Changjin today.

Rong Chao, the company’s legal representative, used to be the planning director of Bona Film and the screenwriter of the movie "Wulin Monster". Therefore, most projects produced by Bona Film can always be seen by the marketing team like a duck to water, but the company is relatively low-key and there is not much public information to inquire about.

In addition to film marketing, such as a duck to water, he also participated in the production of the documentary film "Dragon and Tiger Warrior".

Micro entertainment:

Behind-the-scenes stars and their works in front of the service desk

In addition to Bona’s royal use, The Battle at Lake Changjin’s marketing team has another micro-entertainment company that has cooperated with Bona a lot.

Founded seven years ago, Micro Entertainment has done film marketing for dozens of films such as Chinese Doctors, The Rescue and The Captain’s Later Us and The Four Kings of Di Renjie.

Huang Yiping, the founder, used to be the propaganda director of Tsui Hark Company. Tsui Hark and Bona are deeply bound, so it is not unexpected that the micro-entertainment founded by Huang Yiping has received many Bona projects.

In addition, Micro Entertainment is also responsible for brokerage affairs, providing publicity services for head artists and directors in many fields such as film, television, music and fashion. We have cooperated with Tsui Hark, Rene Liu and Zhang zhen. It can be said that film marketing and celebrity marketing are the two core businesses of micro entertainment.

Small table movie:

Young new forces in film marketing

If you have seen Wrestling! Indian movies such as Dad, Mysterious Superstar and Starting Line, or Japanese film lovers such as Doraemon and Silver Soul, small table movies that are good at young marketing should not be missed.

Zhao Zhuoqun, the founder of Little Table Film, actually studied drama, film and television literature. After several years of hard work in the film and television industry, he made a name for himself in 2015 because he planned the marketing of "Doraemon: Walk with Me", and then he founded Little Table Film and officially cut into the film and television marketing market.

From the initial acceptance of niche projects such as Second Yuan and film criticism, to the present participation in the marketing promotion of popular films such as Seizing the Soul, Bath Buddy, White Snake 2 and Summer Future, Xiaotiao’s ability in creative new media marketing has become increasingly prominent, and the whole team is also very young.

It is worth noting that Xiaotiao Film was invested by Lianrui, a veteran distribution company, in its early days, and now it is backed by Matt Culture, a film and television marketing and production company. YueYang, vice president of Matt, is also one of Xiaotiao’s shareholders.

Dark horse marketing:

Backed by Alibaba Pictures, look at the explosive potential stocks

Dark horse marketing, founded by Du Hao and Andy in 2015, is really a "dark horse" in the film marketing industry:

From Wolf Warriors and detective chinatown series, to Shameful Iron Fist, Flying Life and Ip Man 4, dark horse marketing can be seen behind many explosive films.

In 2019, Dark Horse Marketing was invested by Alibaba Pictures, so most projects in Alibaba Pictures now involve Dark Horse, but it is not limited to this.

This year, Dark Horse Marketing took over many blockbusters such as I want us to be together in Detective Chinatown 3, A Writer’s Odyssey, 1921, Anger and Serious Case, Assassination Storm, etc. Last year, some projects of iQiyi Fog Theater and Youku Suspense Theater were also marketed by Dark Horse.

The names of the brands of Dark Horse are also very interesting, such as basic culture, unlimited imagination, decent culture, whale-like culture and so on. Among them, decent culture has developed well, and participated in the publicity of many projects such as Secret Visitors, First Furnace Incense and Everything About My Mom.

Potato chip culture:

Binding Chen Kexin, Securing High-quality Projects

I first learned about potato chip culture because of the brokerage business of this company: powerful actors such as Tan Zhuo, Ni Hongjie and Lv Xiaolin all cooperated with potato chip culture.

Zhao Jing, the founder of the company, is a senior media person, who once planned and compiled a series of works for director Jia Zhangke.

In 2015, Zhao Jing established potato chip culture, engaged in film and television production, film and television marketing, artist brokerage and other businesses, and participated in the promotion of many high-quality film and television projects such as "Home at One Point" and "Calm Down" in Leap, Better Days.

It can be seen that the company has a close relationship with Chen Kexin’s team. Zhao Jing is the shareholder of Fat Kids Film and Television, a producer in Better Days, and Jo Jo Hui, who has been cooperating with Chen Kexin and Ceng Guoxiang, is the supervisor of potato chip culture.

Collect media:

Focus on the whole case marketing team of film and television

Just four years after its establishment, Jishi Media has participated in the marketing of 50+ popular films such as Psychological Crime, Sewing Machine Band, the richest man in Xihong City, and the ringing of the phone, and its business also involves the promotion of drama series, such as Anjia, Full-time Master, Animal Management Bureau and Sand Sea.

This year, Detective Chinatown 3’s "Secret Visitor", "What Should I Do When My Second Brother Comes" and "Uninvited Visitor" also participated in the collection.

Zhang Weihua, the founder, used to be the general manager of Xiansheng Interactive. After the establishment of Jishi Media, he obtained strategic investment from Joy Pictures. In recent two years, Jishi also established some new companies, such as brand marketing, event operation company, toilet cool entertainment, and Shiguang Interactive.

Taoxiu light and shadow:

New Digital Marketing Backed by Platform

Among the film marketing companies, Taoxiu Light and Shadow is quite special. As a pan-entertainment content marketing MCN organization founded by Alibaba Pictures and Tianxiaxiu in 2018, short video+live broadcast are the two core business segments of Taoxiu Guangying.

Because it can incubate talents independently, Taoxiu Guangying’s film and television announcement does not depend on external delivery. At present, it has customized the layered short video marketing and delivery strategy for The Eight Hundred Leap’s film and television works such as First Furnace Incense and Big Red Packet.

Film marketing is only a part of Taoxiu’s light and shadow business, spanning entertainment content marketing, brand e-commerce live broadcast and other fields. With the creative planning ability of new media and talent matrix, Taoxiu Light and Shadow has become a rapidly rising marketing dark horse in the industry.

Four, four, eight:

Vibrating and blasting money making machine

With short video platforms such as Tik Tok and Aauto Quicker becoming important marketing centers, film marketing companies have also set up short video teams. Short video marketing companies such as "15-20", "Betta Culture" and "Cycling Play" have risen rapidly, and "4-4-8" established in 2019 is one of the leaders.

My Father and I, The Battle at Lake Changjin and Chinese Doctors, Summer Future, Great Dad … Throughout the whole summer and National Day archives, you can see the figure of getting eight out of four in these short video marketing teams.

Yang Yi, one of the founders of "Four-Four-Eight", once worked in Huayi and ByteDance Department, and was quite experienced in film and television marketing and short video planning and operation, which led to the creation of explosive video cases for many film and television projects on the Tik Tok platform.

Immediately film and television:

Mature new army of film and television marketing

As a new company established in October 2020, Lima Film and Television is not well known. The core members of the team are from Road Painting Film and Television, and participated in the marketing promotion of a series of films such as Hi, Mom’s t.a, When Men Fall in Love, Rabbit Violence, online movies Our New Life and Northeast Love Brother.

After obtaining the investment of Fang Ruyi Film and Television produced by Hi, Mom and A Little Red Flower, Ma Yi Film and Television will be responsible for the marketing of Confucianism and Italian projects.

In addition, Lima Film and Television also contacted artists to promote business. For example, Su Ke, the actor of the hit drama "Sweeping the Black Storm", was promoted behind the scenes during the publicity period of the series.

Wei Xiaoli was subverted!

According to electric home news, on August 2, the transcripts delivered by the new car-making forces in July were released one after another. Surprisingly, the monthly delivery champions and runners-up all changed hands. After two months of rapid growth, the growth of new forces slowed down in July.And "Wei Xiaoli" unexpectedly experienced negative growth..Nezha Auto and Zero Run Auto won the first and second place in delivery this month..

Specifically, Nezha, which delivered about 14,000 cars in July, took the top spot in the delivery of new cars by the new force of car making, surpassing Xpeng Motors, which had previously dominated the list. Zero-run cars rose to the second place with a delivery volume of about 12,000 units, with a year-on-year increase of over 177%, hitting a new high for three consecutive months, leading the growth list. Xpeng Motors delivered 11,524 electric vehicles in July, down from 15,295 in June, ranking third. In July, LI and Weilai Automobile delivered 10,422 units and 10,052 units respectively, ranking fourth and fifth, and their chain sales declined. In July, the sales volume of AITO series with deep cooperation between Huawei and Cyrus reached 7228 units, a year-on-year surge of 8873.56%. The delivery of krypton cars reached 5022 units.

For a long time, Wei Lai, Xpeng Motors and LI (collectively referred to as "Wei Xiaoli") are the only protagonists or even pronouns of the new domestic car-making forces. Their business trends or their founders’ remarks have been in the spotlight for a long time, and they have often caused heated discussions. As the first batch of new car companies that have enjoyed the policy dividend and survived smoothly, Wei Xiaoli’s performance is still disappointing. After 7-8 years of establishment, it is close to achieving the annual delivery leap. However, as more and more traditional car companies accelerate their turn, the new force car companies in the second echelon have made great efforts to rush to the capital market. At the same time, they have repeatedly impacted the three-legged pattern of Wei Xiaoli in terms of delivery, and the era of "Wei Xiaoli" will soon be "subverted".

According to the data of the Ministry of Industry and Information Technology, last year, the sales volume of new energy vehicles in China was 3.521 million. According to the Development Plan of New Energy Vehicle Industry (2021-2035), the sales volume of new energy vehicles will reach about 20% of the total sales volume in 2025, that is, about 6 million vehicles. Based on the high growth rate of sales of new energy vehicles in the past two years, the sales volume in 2025 will definitely exceed 6 million, that is to say, it will almost double the market size in 2021. In the first half of this year, the production and sales of new energy vehicles were 2.661 million and 2.6 million respectively, both increasing by 1.2 times year-on-year, and the market penetration rate was 21.6%. The China Automobile Association predicts that there will be more than 5.5 million new energy vehicles in China in 2022, with a growth rate of over 56%. 2025 is a time point that is often mentioned. BAIC Group and Changan Automobile decided to completely stop selling fuel vehicles in 2025. LI will take 20% market share in 2025; Geely has set a target of selling more than 650,000 vehicles in 2025 for its new brand. ……

Obviously, all car companies are eyeing the big cake of the new energy vehicle market, and the competition in the future will only become more intense. It seems that the disintegration of the Wei Xiaoli Iron Triangle is an irreversible trend. Or it can be said that the symbol of the era of "Wei Xiaoli" has completed its mission of opening up the new energy market and completing the basic education of users’ minds, and the next batch of "Wei Xiaoli" will also begin to assume the responsibility as the new protagonist.

In July, the data delivered by the new forces of car-making are as follows:

nextev

Specifically, Weilai delivered a total of 10,052 new cars in July, a year-on-year increase of 26.7%. From January to July, 2022, Weilai delivered 60,879 new cars, a year-on-year increase of 22.0%. As of July 2022, Weilai has delivered a total of 227,949 new cars.

XPENG Motors

In July this year, Xpeng Motors delivered a total of 11,524 units, including 6,397 units delivered by Tucki P7, 3,608 units delivered by Tucki P5 and 1,519 units delivered by Tucki G3i. Since the delivery, the cumulative delivery volume in Xpeng Motors has been close to 220,000 units. Compared with 15,295 units in June, the delivery volume of Tucki in July dropped, with a total of 3,771 units missing. Among them, the two main models, P7 and P5, have significantly reduced the delivery volume. In June, P7 delivered 8,045 units and P5 delivered 5,598 units.

Li Auto

In July 2022, LI delivered 10,422 Li ONE vehicles, and from January to July this year, 70,825 vehicles have been delivered. During the whole delivery cycle, the total delivery volume in Li ONE reached 194,913 vehicles. Compared with the results in June, the ideal also ushered in a certain decline. In June, the ideal delivery number was 13,024 vehicles, which means that 2,602 vehicles were ideal in July.

Nezha automobile

In July this year, Nezha delivered a total of 14,037 new cars, of which 1,382 were exported overseas, a certain improvement compared with 13,157 in June. Nezha has always been known as the dark horse of the new forces. In the past six months, the delivery volume can be said to be rising, and it is often "amazing". From January to July this year, Nezha delivered a total of 771.68 million new cars with the combination of "U+V", and the sales volume of the new cars was close to that of Tucki.

Zero run car

In July this year, a total of 12,044 units were delivered by Zero Run, which was further improved compared with 11,259 units in June, with a year-on-year increase of over 177%. And hit a new high for three consecutive months. Compared with Wei Xiaoli’s short-term decline, zero running without new car baggage is bullish all the way.

GAC AION

Guangzhou Automobile Aian sold 25,033 units in July, up 138% year-on-year; From January to July, the cumulative sales volume was 125,284 units, a year-on-year increase of 135%.

AITO Wen Jie

In July, the delivery volume of AITO brand boundary series in deep cooperation between Huawei and Celestial Automobile reached 7,228 vehicles, a record high and a steady growth from the previous month. Among them, it took only 87 days for Wenjie M5 to deliver more than 10,000 vehicles, which set a new record for the fastest delivery of a single model of a new brand. By July 31st, 2022, the cumulative delivery volume of the M5 was 26,348 vehicles.

Since it was released, the demand for orders of the series has been growing rapidly, but the production and delivery capacity are also affected by fluctuations in the supply chain. At present, Celestial Motors is taking various measures to overcome the pressure brought by the epidemic situation and supply chain, and promote the continuous climbing of production capacity and delivery.

At the beginning of July, the customer M7 was officially released, which is the second model jointly built by Huawei and Celeste after the customer M5. According to the official statement, only 72 hours after the launch of the new car, the number of orders has exceeded 60,000.

Extreme krypton car

As a luxury hunting coupe owned by Krypton Intelligent Technology, in July, Krypton 001 delivered 5022 units, an increase of 16.73% from the previous month, creating a monthly record since delivery. By the end of July, a total of 30,039 units had been delivered. In addition, in July, the large order for Krypton 001 broke through 10,000 again, and the average order amount exceeded 335,000 yuan.

According to Krypton officials, the production capacity of Krypton 001 has climbed rapidly, from 0-10,000 units to 107 days, and from 10,000 to 20,000 units to 64 days. It is expected that the delivery of Krypton 001 will continue to improve steadily in the second half of the year.

Staff: Accurate Music Language

  A special music performance was held in Montpellier, a city in the south of France. Eighteen birds played a wonderful movement on a Gibson electric guitar.

  With the piano entering more and more families, the staff has changed from "familiar face" to "explosive red" among the general public. Because in piano teaching, the notation of staff is widely used all over the world, and only the staff can fully express the music score.

  Notation is to music what words are to language.

  The earliest information of human music can only be preserved from generation to generation through oral instruction. Before the modern high-tech sound carrier appeared, there was only one notation for recording and storing music. At present, the most well-known staff faithfully "writes" the composer’s creative intentions and achievements, which can be called a spectacle created by human music civilization and a microcosm of the emergence and development of music language.

  1. The music recorded on plants opens the notation.

  The earliest origin of staff can be traced back to ancient Greece. Music occupies a very important position in the field of knowledge in ancient Greece. The ancient Greeks used two notations, both of which used letters or similar letters as symbols. One was used to record the melody of vocal music, and the other was used to record the melody of instrumental music. Vocal music notation originated in Ionian at the end of the 5th century BC, and instrumental music notation may be earlier. It is said that the music written in the Vienna National Library on the plant products called Pa Pirus is the oldest music in the world, with a history of two thousand years.

  Some studies also show that a city discovered in 1918, 100 miles southwest of Cairo — — In an ancient ruins in Oxilinkus, researchers found a written record of music — — A hymn fragment written on papyrus. In those days when music was usually spread by word of mouth, even the private remains scrawled on papyrus were extremely rare. This is also the only music record that survived in the first 400 years of Christianity. Above this hymn, the pitch and sound value are recorded by some alphabetic arrangement or simple auxiliary line symbols, which is also a typical feature of the earliest music score format. It has eight different notes, spanning an octave, these letters arranged in a straight line, each note corresponds to a scale, and the scale combination of long and short squares; The horizontal strokes and individual dots on the notes indicate which words should be emphasized when singing.

  In addition, a scholar from the University of California, Berkeley, published an article in 1985, demonstrating that the earliest musical notation was found on the cuneiform tablets originating from the two river basins.

  As the predecessor of staff notation — — Newham notation appeared in the 8th century AD. The word "Neum" comes from Greek, which means "symbol" and is a way to express music in the form of drawing. Since the 8th century, in order to prevent those uncommon hymns from being forgotten because of too long interval, monks who copied hymns added some symbols similar to language stress or punctuation at the top of the lyrics, indicating the up-and-down trend of hymns concisely. This symbol is called "Neum Spectrum".

  In the early days, Newham notation was limited to indicating the direction of hymn tunes, and could not indicate the pitch position and note length. Later, someone creatively used a straight line to mark Newham spectrum to the top and bottom of this straight line, and defined this straight line as F, so the ancestor of staff appeared — — A line spectrum.

  In the middle of the 9th century, a complete hymn melody copied with Newm symbols appeared. In the development of notation, some places began to arrange the upper and lower spatial distances between Neum symbols according to the size of intervals. Moreover, Newham notation indicating the pitch and interval structure of melody has gradually formed, and some symbols can indicate a single note or a group of notes, which helps people to record music melody completely. Later, this Newham spectrum gradually developed into two-line spectrum and three-line spectrum.

  It took nearly four centuries to change from color to black and white.

  Different from today’s black-and-white world, the staff was colorful in the process of reproduction.

  In the 11th century, Guido D ‘Alezzo, a musician in arezzo, Italy, added Newham spectral lines to four lines, and specified the pitch as D, F, A and C, and the range was about eight degrees. Different pitches were expressed by clef or color, and the red line represented F sound, and the yellow line or green line represented C sound, which made the pitch more accurate. This kind of music score was called "four-line score", and they later became high notes in the staff. Since then, due to the need of playing, Newham’s spectrum has appeared six-line spectrum, seven-line spectrum and even eleven-line spectrum. To commemorate the invention and birth of the staff, people called Guido D ‘Alezo "the father of the staff".

  Then, how does the staff come from "stepping on colorful auspicious clouds" return to the black and white world?

  More and more composers are involved in the exploration of more accurate music notation. By the 13th century, the four-line score used all black lines, only a Latin letter was written at the front of the line to indicate the absolute pitch of this notation. This method gradually became popular in Europe at that time. But unfortunately, it still can’t show a clear rhythm. Especially the multi-part melody is becoming more and more complex, and people urgently need to find a way to accurately describe the length of each sound. At this time, a monk named Frank in Cologne, Germany, pioneered the different lengths of "black notes" in his book The Art of Theorem Songs. This notation, which strictly specifies the length of notes, rests and marks, is a supplement and enrichment to Newham’s spectrum and can be called a landmark improvement in the development of line spectrum.

  In the 15th century, the trend of black notes receded, and the types of notes increased, and hollow notes appeared to represent the sound value, which is also commonly known as "white notes". With the development of line spectrum in this period, the position of pitch and the length of sound can be basically recorded, and the Fu Tou has also become a circle.

  In order to change the situation that the spectral lines of musical scores are too many and complicated, European countries later unified Newham spectrum into five lines, and the notes that are too high or too low were expressed by adding lines, which made the recording of pitch more perfect. Since the 17th century, the staff developed on the basis of Newham’s spectrum and quantitative notation tends to be perfect, gradually finalized and has been used ever since.

  After centuries of "tempering", the staff has gradually reached unprecedented accuracy. According to this, composers can mark the changes of volume, speed and timbre more carefully, which can be said to be "presented in detail"

  When water is full, it overflows. Too precise music "language" was later considered by some people as a "double-edged sword". Although it can convey the composer’s creative intention in detail, it squeezes the space for the performer to improvise, which makes the musician shout "not enough". As a result, the direction of notation has changed again, and the final interpretation right of music has been returned to the performers. The performers no longer stick to "accurate presentation" but boldly release their individuality, which makes each performance unique.

  At this point, music notation has gone through thousands of years of development, from being a summary of memos at first, to helping players repeat performances accurately, and then returning to the original point after a big circle.

  3. The first "cross-border" album recording traditional Chinese opera comes from Mei Lanfang.

  In the history of music development in China for thousands of years, there have been many ways of notation, such as subtractive notation, metrical notation, Lv Zi notation, etc. Up to now, except for Gongchi notation, there are a few old folk artists who are using it, and other notation methods are forgotten because they are too cumbersome.

  Accompanied by drums, ancient people sat together, playing games and cheering for fun — — In this way, the embryonic form of early China’s music score was derived from entertainment. Drum music in the Book of Rites Throwing Pots is the oldest ancient music score in China, which appeared in the Zhou Dynasty and has a history of more than 3,000 years. There are some comma symbols in the score, which are arranged vertically in turn, as well as the words "drum", "semi-drum" and "Xue drum". Experts speculate that these are the terms related to performance, and professionals can also simulate the powerful beat from them.

  In Guan Zi Di Yuan Pian written in the Spring and Autumn Period, a mathematical method for calculating the chord length ratio of each tone in pentatonic scale is recorded, which is called "three-point gain and loss method" in history, and the names of pentatonic scale "Gong, Shang, Jiao, Zheng and Yu" in China are completely described. As to where these five names came from, there are different opinions. Some say that they correspond to the stars, some say that they are derived from five animals, and some say that they are totems of ancient clans. All kinds of opinions paint a mysterious color on music and express the different musical concepts of China ancestors. Up to today, little is known about "Gong Shang Shu", but the five tones of "Gong Shang, Jiao, Zheng and Yu" are quite well-known. For example, in the theme song "Long Wen" of Happy Dictionary of CCTV, there is a lyric that "Gong Shang Jiao Zheng Yu, Qin Qi calligraphy and painting sing, peacocks fly southeast, and weaver girls will be cowherd &hellip. …” This song has been sung by stars many times, and it has also been on the Spring Festival Evening in 2010, which became a hit overnight.

  Compared with the western staff and notation, China’s classical music score does not form the accurate quantification of pitch and rhythm and the transcoding of digital symbols, but only the outline record of the basic pitch and rhythm of traditional music or aria, which gives the performers and singers much more freedom and uncertainty in creation than the western music score, so it is also called "frame score".

  The staff was introduced into China in the mid-17th century. There is a written record in Xieyun Duqu, a sequel to Lv Zheng Yi written by Emperor Kangxi in 1713, which published in detail the knowledge of western music theory such as staff, scales, roll names, etc. Although the staff at that time was only in its primary form and its symbols were very different from today’s, it was spread through this printed book.

  The staff, which has just entered the country, is only used to record and spread the classic songs and hymns that praise God sung in the Catholic church. It was not until the end of the 19th century that it was gradually accepted and used by Chinese people. In 1930, Mei Lanfang’s operas were recorded by musician Liu Tianhua for the first time, and Mei Lanfang’s Songs was published, which is also the first "cross-border" album in China to record traditional opera music with staff.

  4. The notation has been carried forward in China.

  There are two kinds of musical notation: numbers and letters. The most common musical notation is numbers, and its embryonic form first appeared in Europe in the 16th century. At that time, a French Catholic priest named Suaiti wrote music songs with seven sounds, namely 1, 2, 3, 4, 5, 6 and 7, and compiled a pamphlet "New Methods of Learning plainsong and Music". In the mid-18th century, Rousseau, a famous French thinker who was famous for his book Confessions, also read the Proposal for New Musical Symbols to the Paris Academy of Sciences, and mentioned the "digital notation". Later, a group of social elites improved and popularized it, and finally formed the notation, which was also called "Galpa-Xie notation" in the west.

  This notation was introduced to Japan in 1882. In 1903, Zeng Zhimao, one of the earliest music theorists in the history of modern music in China, published the article "The General Idea of Music Theory" in a chinese magazine published in Tokyo, introducing the knowledge of western music theory, and published six songs such as "Training" and "Spring outing" in the form of comparison between notation and staff, which is the earliest record of Chinese people using notation at present.

  Shen Xingong, a modern music educator, was also one of the earliest disseminators of musical notation. His School Singing Collection was the first collection of musical notation written and published by China. Since then, notation has gradually spread to schools all over the country. In the 1930s, the mass singing movement of resisting Japan and saving the nation was widely carried out. At that time, famous pop songs, such as March of the Volunteers of Nie Er and The Yellow River Cantata of Xian Xinghai, were written by notation. With the widespread singing of these songs, notation gradually became popular among ordinary people in China.

  The notation of musical notation is the closest to the popular Gong-Chi notation in China, and it is simpler and more accurate to record the height of notes by musical notation. Therefore, musical notation has developed rapidly in China, and some experts even think that China is the country that absorbs and uses musical notation the best and develops it the most in the world. Especially in the field of folk music, notation fits the characteristics of Chinese folk music, because notation records only the general framework of melody, and more needs face-to-face communication between teachers and students; On the playing method of musical instruments, Chinese folk music has many special expressive force symbols, and the use of notation is clear and clear. If staff is used, it will become complicated. These are the important reasons why notation is highly praised by Chinese folk music.

  Of course, this is just a matter of habit. With the blending of modern Chinese and western cultures, more and more folk music also adopts the notation of line notation. In fact, in the field of folk music, there are still many places where staff can be used, and that is the ensemble moment. When all kinds of musical instruments play the same piece of music according to different parts, the powerful function of the staff is revealed, which is unmatched by the notation.

  No one can replace the staff or the simple staff.

  Jacky Cheung, a Hong Kong singer who is known as the "God of Songs" in the Chinese music scene, once bluntly said that he did not know the staff, but only knew the simple music. Nowadays, at the scene of some music variety shows, some judges are repeatedly criticized by netizens because they can’t understand the staff. So, is the staff really more "advanced" than the notation?

  Experts pointed out that in the history of music development, people have created various different notations according to their own needs, and different musical instruments, regions and traditional cultures may produce very different notations. Such as guqin, using guqin notation; Traditional Chinese opera uses the notation of gongs and drums. There is also the traditional notation of Gongchi notation in our country, but now there are the most familiar notation, staff notation and so on. We can’t simply say which notation is the best, but which method is relatively scientific. Through accurate notes and various dynamic symbols and emoticons, we can try our best to return the expression intention of the original composer.

  Objectively speaking, staff notation and simple notation both play an important role in the field of Chinese music culture. They complement each other and have irreplaceable functions, but their users are different.

  Notation is simple and clear. Even now, many popular music still uses notation. Compared with other notation, staff has irreplaceable advantages. It records the level of music by the position of the Fu Tou of the note on five parallel horizontal lines, and indicates the length of the note by the different shapes of the note, which can not only visually indicate the pitch of the musical sound, but also accommodate the music information in a large amount, especially in recording and writing large-scale ensemble music with wide range, numerous parts and frequent tone sandhi. Therefore, since the 18th century, the staff has become the main position of music notation, and it has been widely used in the field of professional music in the world today.

  Nowadays, pianos have entered more and more families. In piano teaching, the notation of staff is widely used all over the world, and only the staff can fully express the music score. At the same time, the performance and singing of various music groups, the teaching of music colleges and the learning of piano children all played a very important role in the spread of staff.

  Can’t clap between concerts?

  At the end of the year, many concerts were held together. Watching a concert is different from watching a movie. There are many unwritten rules, such as not applauding between the movements of a symphony, waiting for a complete track to enter the venue when you are late, and so on. Where did these rules come from that the enthusiastic audience couldn’t understand?

  There was a controversy about whether there was applause between movements. Before the end of 19th century, clapping between movements was "not a thing". Mozart gets excited when he hears the applause of the audience when he plays. Once, in a letter to his father, he mentioned, "There is a passage in the middle of Allegro in the first movement, which I know the audience will like very much … … Sure enough, the audience were all in ecstasy and the applause was very warm. I expected this long ago. When I wrote this paragraph, I knew it would be very effective. At the end of the movement, this piece of music appeared again, and sure enough, the audience shouted again and asked to repeat it … …” Repeated applause made Mozart very happy. After the symphony, he even went to the Royal Garden to buy ice cream to reward himself.

  Until the end of 19th century, there were professional cheering people in European opera houses. The function of these "masters" was to cheer in some boring opera performances. Perhaps this move is not flattering. From the end of the 19th century to the beginning of the 20th century, most audiences accepted the etiquette agreement of not clapping between movements. Moreover, it has been recognized by some composers. For example, in Mourning for the Dead, Mahler even pointed out that there should be no applause in the middle of the movement.

  In addition, there is an important etiquette for listening to the concert, that is, you can’t be late. If you are late for some reason, you must wait for the guidance of the theater staff and wait for a complete track (not a movement) before you can enter. In fact, being late was not condemned as early as the mid-19th century, because early concerts belonged to small gatherings in aristocratic circles, and being late and leaving early was commonplace. By the end of the 19th century, after Mahler was in charge of vienna state opera, he resolutely implemented the rule that late spectators were not allowed to enter the venue, even if the royal family members were late, which became a etiquette until now.

  There is such a saying

  The New Year concert originated from the old Strauss.

  The New Year is a common festival for people all over the world. There are many ways for people to celebrate the New Year, but holding a high-level concert is a program in major cities all over the world, welcoming the beginning of the new year with relaxed and wonderful music.

  The tradition of holding concerts in the New Year originated in Vienna. On December 31st, 1847, Johann Strauss I, the founder of the Strauss music family, held an open-air concert in the suburb of Vienna. The repertoire included symphonies, waltzes and polkas, which were warmly welcomed by the audience, so that the concert didn’t end until dawn the next day. This is the origin of the Vienna New Year Concert.

  Today, the annual New Year Concert held in Vienna Golden Hall is still the most eye-catching annual music event in the world. Most TV stations and radio stations around the world broadcast live, with tens of millions of listeners. Inspired by this tradition, many countries or cities in the world have also held New Year concerts to celebrate the arrival of the New Year.

  Austrian composer’s manuscript sells at sky-high price

  The original manuscript of the score of Austrian composer gustav mahler’s Second Symphony was sold for 4.5 million pounds at an auction held in London, England recently. The 232-page score set a new record for the auction of the score.

  The music seller is the family of Gilbert Kaplan, an American economist and businessman who died two years ago. There is an amazing story behind the score. According to the Daily Mail, Kaplan was fascinated by this symphony, also known as Resurrection, after listening to it at Carnegie Hall in new york in 1965. Never having studied conducting, he is determined to conduct the best orchestra in the world to perform this piece of music one day and put his determination into action.

  Kaplan once described the feeling of listening to Resurrection as follows: "When I entered the concert hall, I was alone, but when I came out, I felt like I was struck by lightning." In the next 17 years, Kaplan traveled all over the world to listen to the performance of this symphony, and discussed his experience with professionals including conductors whenever he had the opportunity. In 1982, he finally stepped onto the stage of Lincoln Center in new york and realized his wish under the witness of many celebrities.

Sports are integrated into the daily life of the people, and the national fitness is full of happiness.

  Participants in the 2017 Xiamen International Marathon. In recent years, marathon has gradually entered people’s lives and become an exercise program for many fitness enthusiasts.

  Xinhua News Agency reporter Wei Peiquan photo

  On April 11th, 2017, the national video conference on mass sports was held, which was the National Fitness Program (2016— After the promulgation of "2020)", the first national mass sports work conference was held. The general assembly adopted the method of "sticking a pole in the end", from the State Sports General Administration and its various departments to the personnel of relevant departments such as sports in various provinces, cities and even counties to attend the meeting. At the meeting, seven units spoke to exchange experiences.

  Sports show multiple values.

  In recent years, people’s health concept has undergone profound changes, and the concept of "exercise is a good doctor" has gradually taken root in people’s hearts. The comprehensive value and multiple functions of sports have been paid more attention to by people, and it is playing a unique role in promoting national fitness.

  Exercise and fitness improve the quality of life. Guangdong province has built community sports parks with physical exercise and leisure fitness functions by using urban corners, flower planting areas, street green spaces and other idle places, and won the "China Human Settlements Model Award" in 2015. "The corner has become a city business card, and the results benefit the people." Wang Yuping, director of the Guangdong Provincial Sports Bureau, said.

  Fitness demand drives the sports industry, which in turn promotes consumption upgrading. Deqing County, Zhejiang Province encourages residents to use social security cards to swipe their cards at designated sports venues for fitness. The medical insurance card has become a "balance treasure" for people’s health. There are 123 sports industry enterprises in the county, and the income in 2016 exceeded 12 billion yuan.

  There is no strict boundary between mass sports and competitive sports. Qiqihar City, Heilongjiang Province takes the combination of physical education and education as the starting point, and selects retired professional ice and snow athletes as primary and secondary school teachers, and the ice and snow physical education curriculum is fully popularized in primary and secondary schools.

  Without national health, there will be no overall well-off society. Gou Zhongwen, director of the State Sports General Administration, pointed out that mass sports is a cause of people’s livelihood, which is related to everyone’s physical and mental health and the future of the nation. "We should fully understand the importance and urgency of doing a good job in this work with a highly responsible attitude towards the people, the country and history, put mass sports on the important agenda, and earnestly grasp the reality and achieve results."

  The event is held by the people.

  This year’s Tianjin National Games will add 19 mass sports events, and the number of mass athletes who only come to Tianjin to participate in the finals is expected to reach more than 8,000. It will be one of the key tasks of mass sports in the new year to give play to the traction and driving role of the National Games and support sports and fitness events around the masses.

  The mass base of table tennis in Beijing is very good. The Beijing Table Tennis Association began to select players in mid-March, and the Beijing folk table tennis team, which was formally formed in early April, began its first training in Xiannongtan Gymnasium. Ning Wei, vice chairman of Beijing Table Tennis Association, said, "The selected players cherish the rare opportunity to participate in the National Games and hope to promote the development of table tennis."

  The development and growth of social sports organizations are indispensable to the success of the sports events around the masses. Since the Shanghai Citizens’ Games was first held in 2012, the local citizens have responded enthusiastically. "We must change the traditional routine of doing everything, get out of the closed circle, and truly respond to the concerns of the masses by opening the door to do sports." Huang Yongping, director of the Shanghai Municipal Sports Bureau, said.

  A variety of activities and events will enable more people to participate in sports, enjoy the joy of competitive sports, and stimulate the enthusiasm of the whole people to participate in physical fitness. Sun Xuecai, director of the Beijing Municipal Sports Bureau, said: "The National Games competition is a great lever, through which more people can participate in sports and gain health and happiness."

  Fitness becomes a way of life

  Nowadays, the elements of sports are "spreading" to all aspects of people’s lives; The masses value the strong positive energy contained in sports.

  Gao Shuping, 50, once won the bronze medal in women’s singles in the National Amateur Table Tennis Championships and got the opportunity to participate in the table tennis competition in the National Games this year. She said, "The happiness that table tennis brings me is beyond words. Although I have not become a professional athlete, I have used this strong energy to train my children and train my son to study in Peking University. "

  At present, people’s treatment of sports is changing from appreciation to participation, from paying attention to the number of gold medals to their own sports environment. This change is reflected in the sharp increase in the number of marathon applicants, the mutual "likes" of sports social platforms, and the increase in social capital’s interest in the involvement of mass sports events.

  Nowadays, more and more enterprises have integrated into all aspects of national fitness. Liu Guoyong, director of the Group Department of the State Sports General Administration, said that in the preliminaries of the mass events of the National Games, different ways were adopted in various places. "Some of them were handed over to the association, while others were open to the market, and whoever did well was handed over."

  In this regard, Gou Zhongwen said that guiding all kinds of market players to participate in national fitness can play its role in activity organization, competition development, scientific fitness guidance and personnel training, and support them to provide personalized and diversified services in national fitness. It can also meet the needs of the masses at different levels, with rapid growth and continuous upgrading.

College students are enthusiastic about growing rice, but the new agricultural science is not as simple as farming.

  "Breakfast, a bowl of boiled rice with pickles, full of rice, sweet back." Eating his own hybrid rice, Liu Haolin, a sophomore majoring in agriculture at the Agricultural College of Sichuan Agricultural University, has an indescribable satisfaction.

  Recently, the news that sophomores successfully planted hybrid rice appeared in Weibo Hot Search. In late April this year, the Agricultural College of Sichuan Agricultural University held a hybrid rice planting and whole growth period management skill competition. Online registration was full just two minutes after it was opened, and many students failed to sign up. In late September, three hybrid rice plants planted by Liu Haolin’s group successfully passed the teacher’s acceptance. Some people praised and others scoffed at the fact that the sophomore boys planted hybrid rice, thinking that it was just the basic skill of agronomy, and some people thought that studying agriculture was just learning to farm.

  Does the popularity of planting competition in agricultural colleges mean that planting is a necessary skill for agronomy majors? What is special about the hybrid rice planted in the competition? Under the background of new agricultural science, what changes have taken place in agricultural professional education in colleges and universities? A few days ago, the reporter of Science and Technology Daily conducted relevant interviews.

  Cutting-edge technology into agricultural competition

  In the eyes of many people, the major of agronomy is to learn farming, and you can learn how to do species work at home without even going to college, so that the farmland can be productive. However, in Liu Haolin’s view, studying agronomy is to contribute to the national agricultural development. "Agronomy taught me how to greatly increase production, how to scientifically farm, how to cultivate new varieties, etc., which is absolutely different from farming at home."

  "This is the public’s misunderstanding of agronomy, which is a modern science that uses science and technology to arm crop production." Ren Wanjun, deputy dean of the Agricultural College of Sichuan Agricultural University, said that planting is one of the most basic skills in agronomy, but in addition to its production function, planting is more important to lay the foundation for theoretical research on crop biology and ecology, new variety breeding, cultivation technology innovation and management model innovation.

  During the competition, in order to let students feel the cutting-edge technology in the field of planting, the college applied the latest achievements of the national key research and development plan to all aspects of the competition.

  In terms of varieties, combined with the adaptability of mechanical transplanting of hybrid indica rice and the demand for high quality and high efficiency, the competition adopted the newly established variety screening index system with "daily yield" and "good taste" as the core; In the two links of seedling raising and planting intubation protection, the high-efficiency seedling raising technology and the green cultivation technology of high-quality hybrid rice with good quality and high quality are adopted respectively.

  The college will organize special personnel to carry out training on the technical application of each link. "The purpose of the training is to enable students to personally experience and master these advanced technologies and help them better cultivate rice." Ren Wanjun said.

  In August, pests first appeared, and Liu Haolin, who wanted to kill insects quickly, accidentally took too many drugs and burned seedlings. As a result, there was no progress when it was time to heading. Liu Haolin, who was thinking about how to feed rice while eating and sleeping, suddenly thought of what the teacher had said in class, so he solved this problem. He said: "Agriculture needs to combine theory with practice. Although there will be setbacks during the competition, the key is to find problems and master methods through practice."

  "The whole competition is equivalent to laboratory planting, and every link can be managed accurately. Because there are fewer seedlings planted in the laboratory, the lighting conditions and soil conditions are not well planted in the field, so its management is more difficult than field planting, but it also exercises and tests students more. " Ren Wanjun said that for scientific research and teaching, laboratory planting is of great value, because each link is controllable, so we can know more clearly the reasons for some phenomena in each link and determine the effect of each technical measure.

  He said that any agricultural research results need to be combined with laboratory and field, and repeated experiments. After the results are planted in the laboratory, they need to be tested by field experiments before they can be popularized, which takes a long period.

  Cross-discipline to create comprehensive talents

  The fiery competition is actually a microcosm of the construction of new agricultural science. In June this year, the Anji Consensus — — The announcement of China Declaration on the Construction of New Agricultural Sciences marks the official start of the construction of new agricultural sciences in China, and the development of higher agricultural and forestry education has entered a new era. Since the announcement of the new agricultural science, what changes have been made in the education of agricultural specialty in colleges and universities?

  "The focus of the new agricultural science is to transform the traditional agronomy specialty with modern biotechnology, engineering technology, information science and technology, so we should focus on combining these technologies with modern agronomy and integrating them into the teaching, scientific research and practice of personnel training." Ren Wanjun said that to take the road of innovation and subject integration, we should not only integrate the latest scientific research achievements and modern high-tech into specialty construction and course teaching, but also deepen the interdisciplinary, strengthen the construction of emerging interdisciplinary fields such as mechanized crop cultivation, precision cultivation, intelligent agriculture and biological breeding, put forward new theories and methods, realize the modernization of agronomy, and let universities lead the development of new agronomy.

  The reporter saw that in the training plan of the college, there are not only basic and professional theoretical courses such as plant physiology, soil and fertilizer science, crop cultivation science, farming science and crop breeding science, but also general courses such as English, ideological and political science, mathematics, chemistry and biology, as well as ideological and political courses for agricultural students to "learn from agriculture and love agriculture" and "strengthen agriculture and promote agriculture". At the same time, interdisciplinary courses such as intelligent agricultural technology and application, agricultural economy and management, plant biotechnology, molecular biology, agricultural industrialization, agricultural standardization and crop production mechanization have also been included in the training plan. Ren Wanjun said that agricultural production should take the modernization road of mechanization, standardization and informationization. As a high-tech discipline, agronomy is a complex comprehensive specialty, so the cultivation of agricultural talents should also be a systematic comprehensive project.

  Innovation and entrepreneurship take on the responsibility of revitalization

  "The most distinctive feature of the new agricultural science in our college is to cultivate students ‘ Willing, capable, hardworking and practical ’ ‘ Sigan ’ Traits. " Ren Wanjun said that agronomy itself has high practical requirements. Under the background of new agricultural science, the mastery and application of technology need to further deepen the practical requirements of agronomy. Therefore, it is particularly important to cultivate students’ practical ability and innovative consciousness.

  "In the process of practical teaching, the most important thing is to cultivate students’ innovative and entrepreneurial ability. In addition to learning the basic operation of planting, students should learn how to solve problems, including theoretical problems, technical problems, production problems, management problems, benefit problems, etc., and constantly optimize their thinking and methods for solving problems. " Ren Wanjun said that agricultural science and technology are constantly developing, and students need to have the ability to innovate, not only to absorb and master new things, but also to continuously develop and create new theories and technologies.

  In order to closely combine practical teaching with the cultivation of innovation and entrepreneurship, the college has established a training path of undergraduate talents with "indoor and field combination, scientific research transformation teaching, classroom cooperation, innovation and entrepreneurship education". In addition to setting up various skills competitions such as hybrid rice planting and whole growth period management, seed quality testing, specimen making, etc. in the school, the college also allows every undergraduate to "join the team, each with a project", so that every student can enter the teacher’s research team, participate in scientific research projects, and cultivate innovation and entrepreneurship ability in scientific research practice.

  In addition, the college has more than 30 off-campus practice bases and expert compound, which can carry out teaching and scientific research practice for students to complete course practice and graduation practice, and serve local economic development while being familiar with actual agricultural production and work. Ren Wanjun said that the College closely combines talent training with the abundant crop resources and diversified production structure in Southwest China, meets the new requirements of the integration and development of rural primary, secondary and tertiary industries in Southwest China through co-construction and co-education in Industry-University-Research, implements the combination of agriculture, education and Industry-University-Research cooperation, and strives to improve students’ comprehensive ability, cultivate a group of high-quality compound agronomists with multi-disciplinary backgrounds, cultivate more new talents who know and love agriculture, and shoulder the responsibility of rural revitalization.

What is the "mobile patrol" for the party group of the General Administration of Sports in view of football corruption?

  On the evening of March 27th, Xinhua News Agency announced the targets of the first round of inspections of the 20th Central Committee. With the approval of the CPC Central Committee, the first round of inspections of the 20th Central Committee will conduct regular inspections of 30 party groups of medium-sized enterprises, "look back" inspections of party groups of five medium-sized financial enterprises, and conduct mobile inspections of party groups of the State Sports General Administration.

  On March 27th, The Politburo Standing Committee (PSC) of the Communist Party of China and Li Xi, leader of the Central Inspection Work Leading Group, attended the national inspection work conference and the first round of patrol mobilization deployment meeting of the 20th Central Committee and delivered a speech.

  Li Xi stressed that to carry out the mobile patrol of the State Sports General Administration, we should focus on fulfilling the party’s leadership functions and responsibilities, implementing the major decision-making arrangements for building a sports power, and thoroughly find out and promote the solution of corruption and deep-seated institutional mechanisms in the sports field, especially in the football field, so as to provide a strong guarantee for building a sports power.

  So what is a mobile patrol?

  The Paper reporter noted that in fact, as early as June 2017, CPC Central Commission for Discipline Inspection website had published an article introducing what a "mobile" patrol was. "Three words and nine words", talking about "mobile" inspections, the comrades of the Central Inspection Team came straight to the point and were concise.

  These "three words and nine words" are "small team", "short and fast" and "swimming whistle"

  “小队伍”指的是每个机动小组5至6人,每个人都是有效“火力点”。“短平快”指的是高效精准突破,直接冲着重点专项问题去。“游动哨”指的是哪里问题反映突出就去哪里,出其不意、攻其不备。

  从李希的讲话来看,这次对国家体育总局党组开展机动巡视直接就是冲着“深入查找、推动解决体育领域特别是足球领域腐败问题和深层次体制机制问题”去的,目标明确。

  那么“机动式”巡视, 中央巡视组用了哪些“招儿”?

  中纪委网站介绍,深入开展“机动式”巡视,有效发挥“机动式”巡视政治“显微镜”、政治“探照灯”作用,中央巡视组亮出三个“招儿”。招式一:抓住关键有的放矢,避免剑走偏锋;招式二:盯住要害机动灵活,不搞面面俱到;招式三:创新方式窥斑见豹,当好“守更人”。

  中纪委文章介绍,“机动式”巡视的巡视组进驻后,盯住单位“关键”部门,精准出击、精准发力。在召开动员会的同时,组织力量深入被巡视单位综合、党务、业务等部门,调取有关资料。从阅看资料入手,了解领导班子结合本单位实际,落实中央重大决策部署和习近平总书记系列重要讲话精神的情况,快速梳理,快速固化,从中发现贯彻落实不够坚决、不够到位的有关问题线索。

  During the inspection, grasp the "key" issues and make a precise breakthrough. Combined with the historical, cultural and institutional characteristics of the inspected unit, the inspection team grasped the key issues related to the performance of the core functions of the inspected unit, deeply understood the situation, found political deviations, achieved accurate breakthroughs, and identified specific problems that were not firm enough and not in place.

  Judging from Li Xi’s speech, the mobile patrol of the State Sports General Administration is to provide a strong guarantee for building a sports power.

  In addition, the "mobile" patrol is to keep an eye on the key points and be flexible.

  Keep an eye on key personnel, have a positive conversation and get to the point. Concentrate time to conduct patrol talks with key positions with relatively concentrated power, adhere to the problem orientation, clearly put forward requirements, and ask them to objectively provide the inspection team with the problems existing in the exercise of power in their own units, departments and positions, and learn some important situations and clues.

  Keep an eye on the key departments and get a deeper understanding of the situation. During the face-to-face talk, listen to the report on the exercise of power by the key work departments of the inspected units, clearly request to strengthen the awareness of problems in the report, measure the work of the departments with high standards, and check the outstanding problems and weak links in the exercise of power by the departments.

At the age of 40, it’s time to prevent osteoporosis.

  After the solar term in beginning of winter, the temperature plummeted. According to the annual clinical consultation, the risk of falls and fractures of the elderly will show an upward trend. This is related to environmental factors such as reduced activity in winter, thick clothes and slippery roads, and also related to physical factors such as aging and degeneration of various organs of the elderly. Today we will focus on the problem of osteoporosis. According to the epidemiological survey of osteoporosis in 2018, 6% of male patients with osteoporosis over 50 years old, 32.1% of female patients, and 51.6% of female patients over 65 years old in China. Our country not only has a high proportion of osteoporosis population, but also does not pay enough attention to osteoporosis. The bone mineral density of people over 50 years old is only 3.7%. In fact, both men and women have entered the early stage of bone loss since the age of 40, and we should prevent osteoporosis from this time.

  1 minute self-examination of osteoporosis risk

  By answering the 1-minute osteoporosis risk test of the International Osteoporosis Foundation, you can quickly know whether you have the risk of osteoporosis.

  1. Parents have been diagnosed with osteoporosis or have been fractured after a light fall.

  2. One of the parents has a hunchback.

  3. The actual age is over 40 years old.

  4. Is there a fracture due to a light fall in adulthood?

  5. Do you often fall down (more than once last year) or worry about falling down because you are weak?

  Has the height decreased by more than 3 cm after 6.40 years old?

  7. Is it underweight (body mass index value is less than 19)

  8. Have you ever taken steroid hormones such as cortisone and prednisone for more than 3 months (cortisone is often used to treat asthma, rheumatoid arthritis and some inflammatory diseases)?

  9. Do you have rheumatoid arthritis?

  10. Have you been diagnosed with gastrointestinal diseases or malnutrition such as hyperthyroidism or hyperparathyroidism, type 1 diabetes, Crohn’s disease or celiac disease?

  11. Do you stop menstruating at or before the age of 45?

  12. Have you ever stopped menstruating for more than 12 months except pregnancy, menopause or hysterectomy?

  13. Did you have your ovaries removed before the age of 50 and didn’t take estrogen/progesterone supplements?

  14. Do you often drink a lot (drink more than two units of ethanol every day, which is equivalent to 570ml of beer, 240ml of wine or 60ml of spirits)?

  15. Currently used to smoking or used to smoke.

  16. Exercise less than 30 minutes a day (including doing housework, walking and running, etc.)

  17. Can’t you eat dairy products and don’t take calcium tablets?

  18. Have you been engaged in outdoor activities for less than 10 minutes every day and have not taken vitamin D?

  As long as the answer to one of the above questions is "yes", it is positive, suggesting the risk of osteoporosis, and suggesting bone mineral density testing or evaluating the risk of fracture.

  Bone mineral density detection is suitable for the following groups

  It is not necessary for everyone to do bone mineral density test. Compare the following self-test options to see if you need to have a bone mineral density test.

  1. Women over 65 years old and men over 70 years old, regardless of other risk factors for osteoporosis.

  2. Women under 65 and men under 70 have one or more risk factors for osteoporosis.

  ■ A slight collision or fall will cause a fracture.

  ■ Adults with low sex hormone levels caused by various reasons.

  ■ Those with diseases affecting bone metabolism or a history of using drugs affecting bone metabolism.

  ■ Patients receiving or planning long-term glucocorticoid treatment

  ■ Small and thin people

  ■ Long-term bedridden patients

  ■ People with chronic diarrhea

  ■ The answer to the 1-minute osteoporosis risk test is positive.

  Remember "Five Origins and Three Stages" in Prevention and Control

  The prevention and treatment of osteoporosis should follow five principles. First, increase bone mass and increase bone peak value; The second is to delay bone loss; Third, inhibit secondary hyperparathyroidism; The fourth is to prevent the first fracture; Fifth, reasonable dietary structure and nutritional composition ratio, quitting bad eating habits, increasing calcium intake, participating in moderate exercise and increasing sunshine.

  Then, according to these five principles, the measures to prevent osteoporosis can be divided into three stages according to age: primary prevention, secondary prevention and tertiary prevention.

  The primary prevention of osteoporosis is to start from childhood, to reach the highest bone mass (peak bone mass) in one’s life from childhood and adolescence to around 30-35 years old, with the goal of avoiding or alleviating the occurrence of osteoporosis as much as possible. There are mainly the following measures.

  Reasonable dietary structure: milk is the most ideal calcium source, with 120mg of calcium per 100ml of fresh milk and a calcium absorption rate of 30%. The daily intake of calcium can be ensured by taking 500ml for adults, 750ml for children and 800ml for adolescents.

  Choose foods with high calcium content: sesame sauce, shrimp skin, dried seaweed, kelp, milk, bean products and cheese are all foods with high calcium content.

  Vitamin D intake: The daily intake of vitamin D is 400IU, and the vitamin D content in foods such as cod liver oil, canned sardines, egg yolk, shad and chicken liver is high. Sunlight irradiation is also one of the important ways to supplement vitamin D. Walking in soft sunshine for 40 minutes can ensure the vitamin D needed by the body. It is best to choose the irradiation time before 10 a.m. or after 3 p.m., so as to avoid too strong sunlight damaging the skin and eyesight.

  Moderate exercise: participating in moderate exercise is helpful to increase bone mass and increase the peak bone mass.

  Adhere to a healthy lifestyle: not addicted to alcohol and tobacco; Drink less coffee, strong tea and carbonated drinks; Less salt and less sugar.

  When people reach middle age, they reach the secondary prevention stage of osteoporosis. The core of prevention at this stage is to delay the loss of bone mass in middle age and try to avoid the first osteoporotic fracture. Women aged 40-49 and men aged 40-64 enter the prophase of bone loss: the annual bone loss rate of women is 0.4%-0.6% and that of men is 0.3%-0.5%. Women enter the period of rapid bone loss 1-10 years after menopause, and the rate of bone loss is obviously accelerated, while men do not have the period of rapid bone loss. In addition to food supplement, physical exercise and a good lifestyle, the main preventive methods need to be supplemented with vitamin D and appropriate calcium. The recommended intake of vitamin D for adults is 400IU/d, and the maximum tolerable intake is 2000IU/d. When vitamin D is used for prevention and treatment of osteoporosis, the dosage is 800-1200IU/d..

  The tertiary prevention of osteoporosis is the stage of mending after the sheep is dead, mainly aimed at the elderly, which is mainly reflected in inhibiting bone resorption, reducing bone turnover rate and preventing accidental injuries and fractures. Osteoporosis can be treated by supplementing calcium and vitamin D and taking anti-osteoporosis drugs under the guidance of professional doctors, so as to avoid osteoporotic fractures and re-fractures as much as possible.

  Calcium supplementation alone cannot replace treatment.

  The daily calcium intake standard recommended by China Nutrition Association is: 400mg; from birth to 6 months; 600mg; for 6-12 months; 800-1200mg; under 10 years old; 11-24 years old 1200-1500mg;; 1400mg; for pregnant or lactating women over 19 years old; Postmenopausal and postmenopausal women who did not take estrogen 1500mg;; Take estrogen 1000mg; for postmenopausal and postmenopausal women; Middle-aged male 1000mg;; 1000-1500mg for the elderly.

  However, calcium supplementation alone cannot replace the treatment of osteoporosis. Osteoporosis patients can’t overcome the obstacle of calcium utilization by bones only by taking calcium orally, so they should be treated regularly under the guidance of doctors.

  About 30% of elderly people over 60 years old and postmenopausal women have gastric acid deficiency. If they have flatulence and constipation after taking calcium carbonate, they should change to calcium citrate. The absorption of calcium citrate is independent of gastric acid and can prevent kidney calculi, which is especially suitable for those with gastric acid deficiency.

  However, whether calcium supplementation is needed or not should be decided by consulting a specialist in a regular hospital and doing a bone mineral density examination. There is a threshold for calcium absorption. Excessive supplementation is not only a waste, but also can lead to kidney calculi’s disease, ectopic calcification and atherosclerosis. Kidney calculi, patients with advanced bone metastasis, hypercalcemia and cardiac and renal insufficiency are forbidden to supplement calcium.
