Whether the scheduled celebration to be held was still under discussion, said the Expo Bureau.Since Aug. 8, volunteers at the Shanghai Expo have put stickers with four Chinese characters "May Heaven Bless Zhouqu" on their uniforms, to call for attention on the mudslide-hit area. On the sticker is a picture of Zhouqu, taken by an Expo volunteer who had just returned from a volunteer teaching program in the county.Donation boxes in the Pavilion of International Federation of Red Cross and Red Crescent Societies have received donations for Zhouqu.

BEIJING, June 18 (Xinhua) -- Many Chinese parents do not like their children using the Internet and a majority of them worry that surfing Internet could negatively affect children's school work, according to a blue paper on Internet use by minors in China released Friday.The blue paper says 42.6 percent of the parents surveyed "strongly oppose their children's use of Internet" or "relatively oppose", while as high as 78.4 percent say they worry that surfing Internet could adversely affect children's study. Another 44.9 percent worry about their children's exposure to pornography online.The blue paper was jointly published by the career development center for Chinese Young Pioneers, the Center for Humanities and Social Sciences Studies by Young Scholars at the Chinese Academy of Social Sciences and the Social Science Academic Press.This was the first blue paper on Chinese youngsters, and the figures in the report were based on a survey conducted from 2006 to 2009, Li Wenge, director of the career development center for the Chinese Young Pioneers, said at a press conference for the release of the blue paper here Friday.Li said the respondents surveyed were elementary and middle school students as well as their parents and teachers in both urban and rural areas, developed and less-developed areas in 11 provincial-level regions in China.According to the blue paper, 46.9 percent of the online community users are under 25 years old.However, there are very few websites designed especially for minors, and children did not know

NGARI/CHENGDU, July 2 (Xinhua) -- Southwest China's Tibet Autonomous Region, known as the "Roof of the World", on Thursday opened its fourth civil airport in farwest Ngari area, shortening a trip to the regional capital Lhasa to one and half hours from three or four days by car.An Airbus 319 landed at Gunsa Airport in Ngari Prefecture at 10:20 a.m., marking the airport's official opening.The passenger flight from Chengdu, capital of the neighboring Sichuan Province, was operated by Air China's southwestern branch.An Air China flight would fly from Chengdu to Lhasa and on to Ngari every Tuesday and Friday, said Bao Lida, a spokesman with the company's southwestern branch based in Chengdu."The flight leaves Chengdu at 5:50 a.m. and arrives in Lhasa two hours later," said Bao. "It leaves Lhasa at 8:40 a.m. and arrives Ngari at 10:20 a.m."At an altitude of 4,274 meters with a 4,500-meter runway, Gunsa Airport is now the third highest airport in the world. Bamda Airport in Qamdo in eastern Tibet and Kangding Airport in Sichuan Province sit 4,334 meters and 4,280 meters above sea level, respectively.Annual capacity of Gunsa Airport is expected to reach 120,000 passengers by 2020.Before the airport opened, Ngari was linked to Lhasa only by road, taking three or four days to cover the 1,600-km route."Bad transportation infrastructure was the biggest bottleneck crippling Ngari's development, but now with a 100-minute flight, I believe it would bring talents and business opportunities to Ngari ," said Dawa Tashi, deputy secretary of the prefecture committee of the Communist Party of China.But the pricey flight fare of 2,590 yuan (382 U.S. dollars) for the 100-minute flight from Ngari to Lhasa might be out of many people's reach in a prefecture where the annual per capita income was only 3,148 yuan in 2009, which was a 16.8 percent increase compared with that in 2008.Construction of the airport began in May 2007 and cost an estimated 1.65 billion yuan (241.22 million U.S. dollars).The flight distance between Chengdu and Ngari is 2,300 km. Tickets can be purchased at several ticket offices, but are not available on the Internet."This is the first time that I flew to Ngari and it was much more convenient than before," said Liu Li, a passenger on the plane.Liu said she and her friends from south China's Guangdong Province and East China's Shanghai Municipality would visit Ngari since they no longer have to come here by bus, which was a difficult journey.Gunsa Airport is the fourth civil airport in Tibet after Gonggar Airport in Lhasa, Bamda Airport in Qamdo Prefecture and Nyingchi Airport.A fifth airport, Peace Airport in Xigaze, is expected to open in October.Exactly four years ago, China opened a landmark railway linking Tibet with major cities, including Beijing, Shanghai and Guangzhou.

WUXI, Jiangsu, June 20 (Xinhua) -- Yuan Longping, known as the "father of hybrid rice", said on Sunday that his team was working on a new version of high-yield hybrid rice and might complete it in 2012.Yuan, director of the National Hybrid Rice Engineering Technology Research Center and a faculty member of the Chinese Academy of Engineering, made the remarks at the World Expo's third theme forum, which opened on Sunday in Wuxi, in east China's Jiangsu Province.The new hybrid, the phase-III super hybrid rice, was expected to yield 13.5 tonnes of rice per hectare, Yuan said.The previous hybrid, the second-generation super hybrid, was released for commercial production in 2006, yielding 9 tonnes of rice per hectare, on averageRice is a major food crop that feeds more than half of the world's population, Yuan said.China is now planting 440 million mu (29 million hectares) of rice per year, with an average output capacity of 6.3 tonnes per hectare.Among the acreage, hybrid rice accounts for about 57 percent of the total, with an average output capacity of 7.2 tonnes per hectare."The average yield of hybrid rice is at least 20 percent more than that of inbred rice, feeding 70 million more people annually," Yuan said.China is faced with a challenging grain situation this summer because of strong rainfalls in the south during the summer harvest season. Other problems include droughts in northern grain production areas and lingering low temperatures in the south.According to the Ministry of Agriculture, China needs to maintain an annual grain output of 500 million tonnes to feed the nation's 1.3 billion people.China's summer grain output rose six years in a row to top 123.35 million tonnes in 2009, which was 2.6 million tonnes more than the previous year."Hybrid rice will play a key role in ensuring food security worldwide in the new century," Yuan said."If 50 percent of the world's rice paddies were planted with hybrids, rice production could be increased by another 150 million tonnes, and 400 to 500 million more people could be fed," he said.Yuan believes food security is "a war people can not afford to lose" ."The global economic downturn will always end, but food security is the problem we have to face every second," Yuan said.Statistics from the United Nations showed about 1 billion people were suffering from hunger and malnutrition and every six seconds saw a child dying of hunger or related diseases.With the theme "science & technology innovation and urban future", the two-day forum focuses on innovations in science and technology.The previous two theme forums of the World Expo centered on communications and cultural heritages.Yuan started working on hybrid rice in 1964."I often drive my car to go to rice paddies to do research," said the 80-year-old, "The only difference is that when I was young, I rode a bicycle or motorcycle ....you could attribute it to improving life."Hybrid rice has also been commercialized in other countries, including India, Vietnam, the Philippines, Bangladesh and the United States."For the benefits of the world' s people, we are well prepared to help other countries develop hybrid rice," he said.
