Beijing, May 29 (Reporter Jing Wong) At 12: 31 on May 28, after a flight of 1 hour and 59 minutes, the flight MU9191 of China Eastern Airlines, which was carried by C919 passenger plane, landed smoothly at Beijing Capital International Airport, passing through the "Watergate" symbolizing the highest etiquette of civil aviation, marking the successful completion of its first commercial flight, officially entering the civil aviation market and opening a new stage of market-oriented operation and industrialization development.

　　This first commercial flight is a milestone from "product" to "commodity" for C919. Guo Qing, an associate professor at the Aviation College of Northwestern Polytechnical University, said in an interview with a reporter from Yangguang. com that the realization of the first commercial flight of C919 boosted the confidence in the development of China’s civil aviation industry, and China’s aviation-related supporting industries will usher in new opportunities.

　　China has officially entered the market competition of world large aircraft production.

　　Large aircraft is known as "the jewel in the industrial crown", which is a concentrated expression of a country’s scientific and technological ability, industrial level and comprehensive strength. "The operation of domestic large aircraft means that China has officially entered the market competition of world large aircraft production, which has made China’s aviation industry move to a higher level." Guo Qing’s analysis also means that in the high-end manufacturing products, China manufacturing can also compete with the world’s large enterprises and stand out from the crowd, which means that the influence of China manufacturing is increasing, which will help to enhance China’s international status.

　　According to "2022 Shanghai Science and Technology Progress Report" issued by Shanghai Science and Technology Commission, by the end of 2022, C919 had accumulated 32 customers and 1035 orders. On April 27th, 2023, HNA Aviation Group and China Commercial Aircraft Corporation signed a purchase agreement for 100 aircraft, including 60 C919 aircraft. Qi Qi, an expert from China Civil Aviation High-quality Development Research Center, told the reporter of Yangguang. com that airlines and leasing companies are extremely optimistic and confident about the commercial market prospects of C919 aircraft, and they are scrambling to sign purchase agreements and strive to get the delivered aircraft and put it into commercial operation earlier.

　　According to Commercial Aeroengine Market Forecast 2021-2040 released by Comac of China, from 2021 to 2040, it is estimated that 41,429 new aircraft will be delivered worldwide, with a value of about 6.1 trillion US dollars. Among them, China aviation market is expected to receive 9,084 passenger planes of 50-seat class or above, accounting for 21.92% of the world, with a value of about 1.4 trillion US dollars, accounting for 22.95% of the world.

　　Qi Qi said that with the commercialization of C919, the trillion-dollar large aircraft industry chain is gaining momentum. "The continuous increase in C919 orders is actually a test of China Commercial Aircraft’s delivery ability, and more specifically, China Commercial Aircraft’s ability to integrate and coordinate the core elements of the C919 industry chain." According to Qi Qi’s analysis, the benefit degree of large aircraft industry chain will be ultimately determined by the annual production capacity and delivery schedule of Comac China. On the basis of ensuring the safe operation and high reliability of aviation, it will be the focus of the next stage to steadily promote and upgrade the localization rate of large aircraft parts, especially core systems and components.

　　Qi Qi believes that the improvement of the localization degree of C919 will fundamentally improve the delivery capacity, stable delivery level and autonomous controllability of Comac China.

　　Orders in related industries such as aircraft supporting manufacturing may surge.

　　After the successful development of C919 large passenger aircraft, customers pay much attention to it. According to reports, according to the international practice of the aviation industry, a model is mature and commercialized on a large scale, and it needs to be continuously optimized and upgraded for many years after entering the commercial operation stage. The reporter learned that in the future, China Eastern Airlines will cooperate with many parties to operate the C919 with high quality and precision, and help make the C919 a successful model recognized by the global industry. "Starting from May 29th, the C919 model will be put into normal operation on the route from Shanghai Hongqiao to Chengdu Tianfu, and with the introduction of this model, the C919 will be put on more routes." Feng Dehua, member of the party group and deputy general manager of China Eastern Airlines, said.

　　Great Wall Securities Research Report believes that, as a representative of high-end manufacturing industry, large aircraft projects have the characteristics of long industrial chain, high correlation and great radiation-driven effect. The development and research of large aircraft projects can effectively promote industrial technology upgrading, promote the process of China’s civil aviation industrialization, and comprehensively promote the development of China’s aviation industrialization.

　　Next, Guo Qing believes that the orders of industries such as metalworking, composite materials, electronic components and chips manufactured by aircraft will surge with the increase of orders of large aircraft. In addition, the education industry will also usher in a "new direction". Aerospace innovation education for young people, aviation majors in colleges and universities, and majors related to industrial chain will all usher in the peak of application, and more young people will devote themselves to China’s large aircraft industrial chain.

　　Scientists discover ferromagnetic quantum critical point evidence for the first time
　　The team of Yuan Huiqiu, a professor at Zhejiang University, discovered the ferromagnetic quantum critical point in pure heavy fermion compounds for the first time, and observed the strange metal behavior. The related results were published online in Nature on March 5. This is the first time that scientists have found conclusive experimental evidence of the existence of quantum critical point in a pure ferromagnetic material system, and observed strange metal behavior similar to that of high-temperature superconductors: when the temperature approaches absolute zero, the low-temperature resistance changes linearly with temperature, and the specific heat coefficient diverges logarithmically with temperature. This discovery breaks the traditional idea that ferromagnetic quantum critical point does not exist, and extends the strange metal behavior to ferromagnetic quantum critical materials, which opens up a new direction for the study of quantum phase transition.
　　Scientists discover accurate diagnosis and treatment of schizophrenia for the first time
　　Biological marker
　　Jiang Tianzai and Liu Bing team of Brain Network Group Research Center of Institute of Automation, China Academy of Sciences, together with researchers from many teams at home and abroad, broke through the bottleneck that the diagnosis and treatment of mental illness only depends on the empirical judgment of symptoms, and successfully established an accurate diagnosis and treatment model of schizophrenia by using multi-group information and artificial intelligence methods. For the first time, the research team found that the abnormal function of the striatum circuit in the brain is a biological marker for the accurate diagnosis and treatment of schizophrenia. Using this biological marker, not only can we quantitatively evaluate the pathological damage of striatum in individual patients, but also can accurately diagnose schizophrenia and predict the individualized curative effect. The imaging marker has been independently verified in patients with mental illness in multiple imaging centers and various populations. The research results were published in Nature-Medicine on March 23rd.

　　Eight "magnifying glasses" relay to simulate the full-scale dark halo clear image of the universe.
　　An international research team led by the National Astronomical Observatory of the Chinese Academy of Sciences adopted a brand-new multiple amplification simulation technology, and obtained a clear image of the internal structure of the full-scale dark halo in the universe for the first time under the current standard cosmological model. The research results were published online in Nature on September 2nd. Dark halo is dark matter halo. It took the researchers five years, with the help of supercomputers, to obtain clear images of dark halos from earth-like mass to giant galaxy clusters, spanning 20 orders of magnitude. It is reported that in a typical area of the universe, this super-magnification simulation needs to be magnified by eight "magnifying glasses", and its magnification is equivalent to finding a flea on a picture of the surface of the moon. The super magnifying glass of computer simulation allows researchers to study the formation, evolution and internal structure of dark halos at different scales in detail. It is found that dark halos with different masses have very similar internal structures, that is, the center is dense and gradually sparse outward. These new findings will help scientists verify the hypothesis about the nature of dark matter-dark matter may not be "completely dark".
　　China’s first superconducting cyclotron was successfully developed.
　　On September 21st, the proton beam energy of superconducting cyclotron independently developed by China Institute of Atomic Energy reached 231MeV for the first time. This is the second time in the world to independently develop a compact superconducting cyclotron after the joint project of the United States and Germany. Researchers have successfully accelerated the continuous proton beam to this energy region, which indicates that China has fully mastered the core technology of miniaturization and high dose rate superconducting cyclotron and entered the international parallel ranks. The accelerator is small in size, low in power consumption and high in beam intensity, and can continuously accelerate 72 million proton beams per second. It is more suitable for fast intensity-modulated scanning therapy, breaking the monopoly of Europe and America in the field of miniaturized precision radiotherapy equipment, realizing the localization of superconducting cyclotron equipment in China, and is expected to greatly reduce the high treatment cost. The accelerator can also be directly used in the research and development of aerospace devices, core chips and integrated circuits, and promote the development of lightweight accelerators for aerospace particle beam applications, further opening up new fields of proton science research and application in China.

　　QQSmall games are connected to Tencent Health System to upgrade the protection ability of minors.

　　Recently, QQ games have been officially connected to Tencent Health System, which will help parents to plan the game time of minors and help them grow up healthily through the unified real-name authentication function and the ability of minor users to play and pay. This capability will be realized by the platform, and it is gradually covering all small game users.

　　Users who are certified as minors will not be able to use small game services from 22: 00 to 8: 00 the next day; The legal holidays shall not exceed 3 hours per day, and the other days shall not exceed 1.5 hours per day. At the same time, minor users will also be restricted in the use of paid services, and different age groups will be restricted by different levels of consumption. At the same time, parents can also pay attention to WeChat official account, the "growth guardian platform" in QQ, to control the total duration and consumption of various games played by children, and to guide children to develop healthy playing habits.

　　Resolutely crack down on fraud and ensure the safety of minors online.

　　Combined with the hot spots of online classes, criminals are constantly renovating scam routines, such as sneaking into study groups, changing their nicknames and avatars into the same style as teachers, and defrauding parents and underage students of their money in the name of paying information fees and training fees. For this kind of illegal behavior, QQ security team has continuously upgraded its security strategy and crackdown measures in combination with many years of "black ash production" confrontation experience, "black ash production" big data and AI capabilities, and actively assisted relevant competent authorities to jointly crack down on crimes that endanger network security.

　　According to the statistics of the first quarter of 2020, the QQ security team has blocked the counterfeiters from deceiving their parents about tuition and miscellaneous fees, lurking in more than 6,000 related home-school groups, and protected the property safety of more than 300,000 students and parents. At the same time, the bingo anti-fraud prevention and control system based on Tencent’s years of experience in "black production" confrontation, massive big data and machine algorithms has identified 60,000 fraud warning messages and output them to the police, including 7,000 training fee fraud warning messages. The police have effectively intercepted and dissuaded the victims. In addition, the QQ security team also cooperated with Tenpay Risk Control to intercept fraudulent risk transactions amounting to more than 2.5 billion yuan, including nearly 100 million yuan of training fee fraud.

　　In the face of the internet world with complicated information, helping to protect the healthy growth of minors has always been the direction of QQ. In the scene of online classes, QQ continues to combat prevention through function optimization and related criminal acts, hoping to provide students with a more efficient and safe learning environment and help them better cope with the learning pressures and challenges in a special period.

West Ham United VS Arsenal

After West Ham lost to Everton at home last season, the league suffered two consecutive defeats. The team’s recent performance is really not safe, and it is still difficult to resist when facing the league’s strong teams. At present, it ranks 9 th in the league. West Ham United’s offensive output is acceptable, but the stability of the team’s defense is still insufficient. After Arsenal’s victory over Sheffield United, the league remained unbeaten, and the team is currently ranked second in the league. Arsenal’s offensive output is very strong, and the stability of the defense line is also worthy of praise. Recently, it has been able to score zero opponents in many games.

West Ham United’s overall strength is relatively limited, the team’s recent stability is not high, and the main battle performance is not safe. The Arsenal League has guaranteed unbeaten record so far, and the team’s historical achievements have crushed opponents, so the psychological advantage is very obvious. This time, the team is a guest to challenge their opponents, and I believe that they still have the ability to win from the away game.

Everton VS Burnley

Everton beat West Ham United in the last league. The team’s recent achievements are relatively erratic, showing a plum blossom pile, but its winning ability has indeed improved, and it is currently ranked 15th in the league. Everton’s offensive and defensive ends have also improved to some extent recently. Burnley lost to Bournemouth in the last league, and the league suffered another three-game losing streak. So far, the team has only won one victory, ranking only 19th in the league. Burnley’s offensive output is relatively weak, and the defensive end can be said to be full of loopholes.

Everton’s recent performance is indeed unstable, and the team has no strength against the strong teams, but its winning ability has indeed improved in the face of the weak teams in the league recently. The performance of Burnley, the opponent, continued to be sluggish, and recently suffered a three-game losing streak. This time, Everton is sitting at home to meet the challenge of the weak team, and I believe that I still have the ability to successfully win the opponent at home.

Bournemouth VS Liverpool

Bournemouth defeated Burnley at home in the last league, and finally won the first victory in the league. However, the opponent is really a weak team, and the gold content is really not high. At present, it still ranks 17th in the league. Bournemouth’s front line output is insufficient, and the loopholes at the defense end are not small. Liverpool beat Nottingham Forest at home last season, and the league won two consecutive victories and three unbeaten games. The overall performance of the team has once again strengthened, and it is currently ranked fourth in the league. Liverpool’s offensive output is stable and the defense strength is constantly strengthening.

Bournemouth’s overall strength is very limited, the ability to fight hard is also insufficient, and there is no advantage at home. After all, Liverpool, the rival team, has recently returned to the right track after losing the game unexpectedly, and the stability of both offensive and defensive ends is constantly improving. In addition, Liverpool’s historical achievements have crushed their opponents, and even if they are a guest, they are not afraid.

Manchester United VS Newcastle United

Manchester United lost to the opponent in the last Manchester derby, and was hit by the strong team after winning two consecutive victories. However, the team has won several victories in the near future, and its overall performance has improved. At present, it ranks eighth in the league. Manchester United’s offensive and defensive stability needs to be strengthened. Newcastle United drew away with Wolves in the last league, and the league remained unbeaten in six rounds, but the winning ability was still insufficient, and it is currently ranked sixth in the league. Newcastle United’s offensive output is strong, but the defensive end often has problems.

Manchester United’s domestic and foreign troubles are serious, and the recent achievements and performance of the team are indeed not stable enough. However, as for Chi Hah, he still needs to strive for victory in every game to stabilize the morale of the army. Newcastle United’s overall performance has been stable recently, but its winning ability has indeed declined. In addition, the team’s winning ability in guest games is indeed insufficient. This time, the Red Devils welcomed their opponents at home, and I believe there is still a chance to successfully win their opponents.

Chelsea VS Blackburn

Chelsea lost to brentford at home last season, and the unbeaten game in three rounds of the league ended. Losing the game is really unacceptable, and it is only ranked 11th in the league at present. Chelsea’s offensive output suffered another zero, and the defensive end of the last two league games also lost 2 goals per game. Blackburn lost to Swansea at home in the last league, and its three-game winning streak ended. It is rare for the team to win a winning streak in the near future, and the last game was also ended by opponents. At present, it ranks 12 th in the British Championship. Blackburn’s offensive output is also not stable enough, but fortunately the defense strength has improved recently.

Chelsea’s defeat on the road to the Northern Expedition was indeed a blow to morale, but this time the team ushered in a lower-level league opponent, which was also a rare opportunity for the team to snatch victory and revive morale. Opponent Blackburn rarely won a winning streak recently, but the stability is still insufficient. The last game was terminated by the opponent, and the efficiency of the team’s offensive end really needs to be strengthened. This time, Chelsea played at home to meet the challenge of Championship team Blackburn Rovers. I believe it is not too difficult to win the opponent.

Dortmund VS Hoffenheim

The recent performances of both sides are relatively stable, but Dortmund’s achievements in the past battles have crushed opponents, and their psychological advantages are very obvious. This time, I took a strong home game against my opponent, and I believe I still have the ability to continue my outstanding achievements.

Frejborg VS paderborn

Although Frejborg’s performance is erratic, he has a strong ability to score points in the main battle. Paderborn, the opponent, is a team in the middle reaches of German B, and its overall strength is relatively limited. I’m afraid it’s very difficult to be a guest and challenge Frejborg.

Hertha Berlin VS Mainz

Hertha Berlin’s current situation is erratic, but it is good to win more and lose less, and at the same time, the main battle ability is not weak. Although the opponent Mainz is a high-level league team, the team’s performance so far has not been satisfactory. This time the two sides met, Hertha Berlin still had a chance to defend the unbeaten home.

Udinese VS Cagliari

Udinese’s winning ability is limited, but his recent performance is fairly safe. Although the opponent Cagliari won the first victory in the league in the last campaign, the overall stability is still insufficient, and at the same time, the ability to fight is not good. This time, Udinese is at home, and I believe he still has a certain advantage.

A few days ago, Chanel led the establishment of Traceability Alliance for Sustainable Cosmetics (TRASCE). According to the official introduction, TRASCE Alliance was established to deal with destructive events in the cosmetics supply chain, including health crisis, climate crisis-related events and geopolitical challenges.

The alliance consists of 15 beauty companies including Chanel, Clarins, Dior, Estee Lauder, L ‘Oreal, Shiseido, L ‘Occitane and Sisley, and international raw material packaging suppliers.

In recent years, international beauty giants have continuously increased the number of sustainable beauty cosmetics and formed industry alliances with the goal of environmental protection and sustainability. In February 2022, 36 international beauty care groups, including L ‘Oreal, Henkel, Unilever, LVMH and Natura &Co, announced the establishment of the Eco-Beauty Score Consortium, aiming at establishing a brand-independent and transparent cosmetic environmental impact assessment and scoring system for the whole industry.

On the road of promoting the sustainable development of beauty, international brands are indeed at the forefront, and may be more than one position ahead of domestic brands. For example, L ‘Oré al promises that by 2030, 95% of the ingredients in the brand formula will be bio-based and 100% of the plastic packaging will be recyclable; Unilever’s goal is to achieve zero emissions of all products from production to sales by 2039; By 2030, P&G will achieve 100% FSC certification and so on.

International brands have the first-Mover advantage in the field of sustainable beauty, and occupy the right to speak in the international market. However, the formation of the alliance, to a certain extent, is also shaping the brand authority. It is not excluded that they hope to re-divide the global market position and create barriers to industrial competitiveness through the form of alliance, which may increase the difficulty of domestic products going to sea and further raise the threshold for China brands to enter the European and American markets.

01 "abandoned" natural organic

Ten years ago, "organic", "natural" or "plant" skin care products were all the rage in China market. With the popularization of basic knowledge of ingredients, formulas and efficacy of skin care products in the industry, consumers found that "natural and organic" did not mean safer and more effective, and skin care products with scientific basis and clinical efficacy were more popular with consumers.

Therefore, many imported brands focusing on the concept of "natural and organic" have lost their reputation in the China market. Only last year, British organic skin care brand Aurelia, Japanese natural organic make-up brand Naturaglace, New Zealand natural skin care brand Snowberry and other natural organic brands closed Tmall flagship stores in China.

The concept of "natural and organic" is no longer the golden key for foreign minority brands to open the door to China market. More importantly, from the perspective of national policy supervision, China has never really opened the door for "natural and organic" beauty cosmetics.

On July 1, 2012, China cancelled the organic certification of cosmetics, and in 2015, the words "organic", "pure natural" and "0-added" were included in the prohibition language of cosmetics labeling in the Measures for the Administration of Cosmetics Labeling. As soon as the policy comes out, it basically means locking up the growth space of natural and organic concepts in the beauty market in China.

Not only that, international beauty giants seem to be deliberately giving up the concept of natural organic. In November 2023, L ‘Oré al sold Sanoflore, a natural skin care product, to private equity firm Ekkio Capital in a low-key way. Earlier, L ‘Oré al Group sold The Body Shop to Nature&Co Group.

It can be said that natural organic beauty cosmetics died early before they rose in the global market, but it did not affect the concept of planting grass in consumers’ minds. More importantly, green, healthy and sustainable development is the development trend that all major industries in the world are following.

According to the data of White Paper on Pure Beauty Industry, from 2020 to 2027, the global pure beauty market is expected to grow from 5.4 billion US dollars to 11.6 billion US dollars, with a compound annual growth rate of 12.07%. In China, 86% of China users said they would consider using Clean Beauty products, and the number of pure beauty users in Amoy increased by more than 31% year-on-year.

According to Bain’s Insight into Sustainable Consumption Trends in the Asia-Pacific Region, 90% of the respondents are willing to pay a premium for the sustainability of products, and as many as 51% of the respondents regard environmental protection as one of the three most important shopping standards.

Compared with natural organic and pure beauty, sustainable beauty can be regarded as a higher-level version. At present, domestic and foreign brands are constantly "washing green", and the mass society will also pay attention to how brands practice the principles of "openness, transparency" and "traceability", such as sustainability in raw materials and research and development; Environmental protection in production, terminal, packaging, logistics and so on. "Natural and organic" is being reborn with the concept of "sustainable beauty".

02 domestic beauty cosmetics catch up with the sustainable wind

At present, there is no clear definition of sustainable beauty at home and abroad, but it is generally believed that sustainable beauty includes two dimensions: content sustainability and packaging sustainability.

In terms of contents, sustainable beauty cosmetics pursue minimalist ingredients, safety, transparency, naturalness, organic, traceability and environmental friendliness. In the outer packaging, sustainable beauty should adopt recyclable materials, recycled raw materials and reusable packaging design. In addition, in the production, research and development, circulation and other links, brands should also implement more energy-saving and emission-reduction measures as much as possible.

For international beauty brands, sustainable beauty has become a must for brand development.

In the second half of last year, sustainable beauty became the darling of the international capital market. Yepoda, a natural skin care brand with sustainable concept in Korea, completed the A round of financing; Líha Beauty, a British aromatherapy natural and sustainable skin care brand, received an investment of 1 million pounds; Iris&Romeo, a "pure" beauty brand, has been invested by True Beauty Ventures and so on.

Back in the domestic market, compared with the prohibition of natural and organic concepts in the field of beauty, the state is encouraging the development of sustainable beauty.

Previously, the "Implementation Plan for Promoting Green Consumption" jointly issued by the National Development and Reform Commission and other seven departments clearly stated that by 2025, the concept of green consumption in China will be deeply rooted in the hearts of the people, and the green transformation of consumption in key areas will achieve remarkable results, and the green consumption mode will be widely implemented, and the consumption system of green and low-carbon circular development will take shape; By 2030, green consumption mode will become the conscious choice of the public, green low-carbon products will become the mainstream of the market, and the green low-carbon development model of consumption in key areas will basically take shape.

Under the guidance of sustainable development and green consumption, many domestic head beauty enterprises are vigorously promoting ESG construction.

Bettini, Nature Hall, shanghai jahwa, Polaiya and other brands are already releasing ESG reports, planning outlines and proposals. In the report, Polaiya Group disclosed that in 2022, the per capita office power consumption will be reduced by 4.36% year-on-year, and the per capita office water consumption will be reduced by 13.27%. Carbon dioxide emissions will be reduced in raw material procurement, product production, product packaging and logistics transportation, and the accumulated carbon emissions will be reduced by 2,261.23 tons. Betani guides the development of packaging through three major directions: new structure and new material, plastic reduction and non-plastic, and introduces the concept of green packaging from the design end.

Alexandra Palt, Chief Corporate Responsibility Officer and CEO of L ‘Oré al, once said that through the topic of environmental protection, brand value can be better enhanced, thus guiding consumers’ consumption choices. The brand’s sustainable development and sense of social responsibility can affect the purchase behavior of individual consumers, and consumers’ recognition of sustainable beauty can also promote the brand’s development in this field.

Sustainable beauty should not only be a marketing concept, but more brands need to practice sustainable development with practical actions. China’s beauty industry needs to participate more in the international sustainable beauty alliance, and establish its own alliance system and standard system, so that sustainable beauty will become the outlet to promote the development of the industry in the "post-ingredient era".
