Air pollution with a high level of PM2.5 forms a haze of smog at Victoria Harbour in Hong Kong last year.Chan Longhei/ For China Daily A team of researchers in Hong Kong is working on an application that will draw on artificial intelligence and big data to guide people away from air pollution hot spots, as Sylvia Chang reports. With more than 1,700 deaths blamed on air pollution in the past year, Hong Kong is badly in need of help. It is on its way in the form of an air pollution map produced with artificial intelligence. However, it will take about five years for the application, designed by researchers at the University of Hong Kong, to emerge from the city's miasma of nitrogen dioxide, sulfur dioxide and ozone. The map, capable of producing real-time readings or predictive analysis, will reveal where concentrations of toxic emissions are, and where they are likely to go. The app will not solve the pollution problem but it will allow people to see what they are getting into, and let them know if it would be better to change their plans. The readings will show the concentration of pollutants right down to the level of the street they are on. Badly polluted air can make outdoor exercise a health hazard, because tiny particles 30 times smaller than a human hair, known as PM2.5, can find their way deep into the lungs. The app will allow someone training for a marathon, children with physical education classes scheduled and people suffering from asthma to check PM2.5 levels and stay away from high concentrations, or even postpone training or going out that day. According to the Hedley Environmental Index designed by the School of Public Health at the university, known as HKU, air pollution was responsible for about 1,780 deaths in Hong Kong in the past year. Like a smartwatch, the system will be able to track a person's fitness and activity level. But, more important, it will also read the air quality and even forecast it for the next hour or next day. That means it will be able to advise individuals about suitable activities based on both air quality and their personal health and fitness. Researchers say it will provide estimates of PM2.5 concentrations for any geographical area in Hong Kong, down to the hectare level. It's like weather reporting, on a real-time basis, to the street level, said Victor Li On-kwok, chair professor of information engineering at the university's Department of Electrical and Electronic Engineering, who is leading the team studying the system. black rubber braceletsyouth wristbandswristband creationcool wristbandsrubber wristbands custom cheaptrio spinners
A flag-raising ceremony on Sunday at Golden Bauhinia Square in Hong Kong marks the 21st anniversary of the city's return to the motherland. ZHANG WEI/CHINA NEWS SERVICE SAR has experienced steady economic growth with lower unemployment rate One year ago, President Xi Jinping called upon the people of Hong Kong to redouble their efforts, leverage their strengths and build their economy under one country, two systems. His remarks have energized and reinvigorated the special administrative region, as the city has boasted a banner year ever since. Since the president's inspection tour on June 29 through July 1 last year, Hong Kong has experienced steady economic growth. The polarization that divided the city is now less fractious, and the SAR has achieved even greater integration with the Chinese mainland. There are also new initiatives to help the people of the city, especially the young, to achieve their hopes for a better future. Xi promised the central government's firm support as he set out his vision for Hong Kong's development, marking the 20th anniversary of the SAR's return to the motherland. Today, government officials, the business community, emerging entrepreneurs and university students concur that the president's encouragement has brought about important advances in Hong Kong's progress. The city's GDP increased by 3.8 percent in 2017, and registered 4.7 percent growth in the first quarter of 2018. The 2.8 percent unemployment rate from February to April this year was the lowest in two decades. Belt and Road Initiative Hong Kong's participation in the Belt and Road Initiative and the Guangdong-Hong Kong-Macao Greater Bay Area development, with strong support from the central government, presents the city with exceptional opportunities toward greater prosperity. The city's strategic position in both the Belt and Road Initiative and the Greater Bay Area assures its continued status as an international center for free trade. During the past year, Hong Kong has signed free trade agreements with Georgia and the Association of Southeast Asian Nations, advancing the city's significant role in the Belt and Road Initiative. Aron Harilela, chairman of Hong Kong General Chamber of Commerce, said businesses in the city are ideally placed to capitalize on these developments, particularly within the Guangdong-Hong Kong-Macao Greater Bay Area. The chamber's regular business missions to the Greater Bay Area have shown that the initiative is already having an impact. Cities within the cluster, some of them hubs for technology and advanced manufacturing, are eager to work closely with their neighbors for mutual progress, Harilela said. Innovation-tech hub Xi issued an instruction in May to accelerate Hong Kong's development as an international center for innovation and technology. He issued the instruction responding to a letter from 24 Hong Kong-based academicians from the Chinese Academy of Sciences and the Chinese Academy of Engineering. The Ministry of Science and Technology and the Ministry of Finance, as a result, announced that Hong Kong's universities and other scientific institutions may apply directly for funds from the central government. The funds, previously available only on the mainland, may now be used in Hong Kong. The president's directive offers insight into the great importance the central government attaches to Hong Kong talents and potentialities in science and technology. It also gave a shot in the arm to the city's development, said the special administration region's Chief Executive Carrie Lam Cheng Yuet-ngor. In its 2018-19 budget, the HKSAR government set aside HK$50 billion ($6.37 billion) for innovation and technology development. An interdepartmental Steering Committee on Innovation and Technology, led by the chief executive, also was established. In addition, the Technology Talent Admission Scheme, a three-year pilot program that kicked off on June 25, offers a fast-track on visa applications from global talents. Additional resources have been invested in the city's innovation-technology industry, as outlined in Lam's first Policy Address, delivered in October. Hong Kong already is recognized for its sound technological foundations and outstanding capability in scientific research. Lam acknowledged at a recent summit that this success may be credited to the cooperation among top universities, research institutes and high-quality talents from around the world. Combining the unique advantage of one country, two systems, the vast mainland market, and support from the central government, Hong Kong is predicted to evolve into a world-class innovation-technology hub and smart city, Lam added. Exchanges Another area that Xi particularly emphasized during his inspection tour last year, was to provide greater convenience for Hong Kong people to study, work and live on the Chinese mainland. In August and December, the Hong Kong and Macao Affairs Office of the State Council announced two sets of measures easing the path for Hong Kong people on the mainland in education, employment, business and travel. Probably the most timely and important measure is the phasing out of the employment permit requirement for Hong Kong people working on the mainland, said Kuo Waikeung. Kuo is a Hong Kongborn entrepreneur, operating a startup in Qianhai, a free trade zone in Shenzhen. Qianhai is the first area to implement the new policy. A two-year employment permit had been required of residents from the Hong Kong and Macao special administrative regions and Taiwan since 2005. Kuo said the change meant his company's Hong Kong employees no longer need to extend their work permits when their contracts expire. The time it takes to recruit new employees from Hong Kong has been reduced by at least two months. Another central government policy, giving Hong Kong and Macao people equal access to the mainland's housing fund, has also been implemented in Qianhai, Shenzhen, according to Witman Hung Wai-man, a Hong Kong deputy to the 13th National People's Congress. Exchanges with the mainland and greater exposure have become more frequent and intensive for Hong Kong's youth. Through internships and guided tours, young people gain greater knowledge of the country's development. Andy Tsang Hin-lam, a freshman history major at the Chinese University of Hong Kong, joined a youth delegation in late June, and visited Shenzhen, Wuhan, Hubei province, and Beijing. Tsang said he was surprised and inspired by the rapid development of technology on the mainland. Hong Kong's development has always pulled at my heartstrings, Xi said when he arrived in Hong Kong on June 29 last year. In a series of speeches Xi delivered during his inspection tour, he emphasized the importance of setting aside differences to find common ground and unite for the greater good of the city's future.
