BEIJING, Jan. 8 (Xinhua) -- China started the Spring Festival peak travel season Sunday, with tens of millions of passengers, mainly migrant workers and college students, on the move in the world's largest seasonal migration.The Spring Festival, or Chinese Lunar New Year, fall on Jan. 23 this year. It is the most important traditional Chinese festival for family reunions.A total of 3.16 billion passenger trips are expected during the 40-day peak travel season, or Chunyun (Spring transportation) in Chinese, up 9.1 percent from a year earlier, according to the National Development and Reform Commission.

BEIJING, Sept. 30 (Xinhuanet) -- China's space dream took a step closer to reality as the Tiangong-1 module blasted off into the night sky on Thursday from the Gobi Desert.The Long March II-F T1 rocket, under the unmanned module, Tiangong-1, lifted off from the Jiuquan Satellite Launch Center at 9:16 pm as planned.Ten minutes later Tiangong-1 separated from the rocket on its way to orbit, 350 kilometers above Earth. The module deployed its two solar panels, which provide power, at 9:28 pm.At 9:39 pm, Chang Wanquan, chief commander of the manned space program, declared the launch a success as cheers and applause echoed around the command and control center in Beijing.President Hu Jintao and other members of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee went to the center to witness the launch.Premier Wen Jiabao watched at the Jiuquan Satellite Launch Center as the Long March rocket, carrying the space lab, blazed into the night sky.The launch paves the way for China's first rendezvous and docking mission. An unmanned Shenzhou VIII spaceship will be launched in November to dock with Tiangong-1.Two more missions are scheduled for next year and astronauts will board Tiangong-1, which can also function as a space lab.If the mission succeeds, China will become the third country to master spacecraft rendezvous and docking technology following the then Soviet Union and the United States, experts said.Wu Ping, the space program's spokeswoman, said that the ability to rendezvous and dock is vital for building a space station, which China has scheduled for around 2020."A space station cannot be launched in one shot. The modules must be launched separately and then assembled in space," she said.China has invested 35 billion yuan (.47 billion) in total on its manned space program since 1992, when it was approved, she told China Daily.The first phase, from 1992 to 2005, accounted for 20 billion yuan. During this period, China launched six Shenzhou spaceships to set up a system transporting astronauts between Earth and space.In the second phase, from 2005, 15 billion yuan has been spent on projects, including Shenzhou VII and the first rendezvous and docking mission, she explained.Zhou Jianping, chief designer of China's manned space program, said that the space lab and future space station provide a rare platform for conducting experiments that could lead to breakthroughs in the study of materials and biological pharmacy."Experiments made in the microgravity of space can lead to unexpected results," he said.For example, gas and liquid are unable to mix on Earth, but in space they mix naturally, he said."The primary purpose of China's manned space station is to peacefully explore space, and through it, serve mankind," he said.Some have questioned the participation of the military in the program. However, the military has experience in coordinating large-scale requirements that are vital for the program and their involvement reflects international norms, Ministry of National Defense spokesman Geng Yansheng said on Wednesday.He reiterated that China is firmly opposed to the weaponization of space and the program is peaceful.China is now in the second phase of its manned space program. The goal of the program, which has three steps, is to build a 60-ton space station around 2020.The second phase focuses on mastering four key technologies for assembling a space station.The first of these, extravehicular activity, was completed successfully in 2008 after Shenzhou VII was launched.Rendezvous and docking is what is being experimented with. The third technology involves cargo spaceships ferrying supplies to a space lab. The fourth tackles problems concerning the prolonged sustaining of life on a space lab, especially recycling air and water.Besides the manned space program, China launched two lunar orbiters in 2007 and 2010. It plans an unmanned lunar landing around 2013, and returning moon samples in 2017.

ATHENS, Nov. 11 (Xinhua) -- The third Forum on the Development of Tibet concluded here on Friday after discussions on efforts to promote the world's understanding of Tibet and enhance the cooperation between China and the rest of the world with regards to Tibet's development.This year marks the 60th anniversary of Tibet's peaceful liberation. During the two-day event, delegates from Greece, Britain, France, Germany, India and Nepal expressed their opinions on Tibet's modernization and put forward valuable advice and suggestions based on their own experience and research findings.Some of the foreign delegates have visited Tibet many times before. Narasimhan Ram, Editor-in-chief of The Hindu from India and Brendan O'Neill, editor of the British magazine Spiked spoke positively about the preferential polices and financial support of the Chinese central government and other parts of China for the region.During the Forum, Wang Chen, head of the Chinese State Council Information Office met with the Greek political leaders and journalists from mainstream media.People got an opportunity to learn more about China as Nyima Tsering, Vice Chairman of the Standing Committee of the People's Congress of the Tibet Autonomous Region, introduced the development of Tibet and the Chinese government's policy towards the region.A number of Greek mainstream media covered the Forum.Over the past 60 years, Tibet has achieved a huge development in both its social structure and socio-economic development, said a communique released upon the end of the forum.It also foresees a great potential of cooperation with the international community in energy, environment, education and healthcare development for the region.The forum has facilitated better understanding of Tibet in the international community and will help to promote faster and better development of the autonomous region, the Communique said.

WASHINGTON, Nov. 16 (Xinhua) -- Supervised exercise was shown to be more effective than stenting or medication for improved walking ability in patients with peripheral artery disease (PAD), according to a U.S. study reported Wednesday at the 2011 American Heart Association Scientific Sessions meeting.The research group reported that of 111 patients studied in the randomized trial, the most effective treatment proved to be supervised exercise based on the results of a treadmill test taken at baseline and again at six months. Patients who were in the supervised exercise group improved by a mean of 4.6 minutes in the treadmill test, while the group who received stents improved by a mean of 2.5 minutes. However, researchers found that self-reported quality of life measurements proved to be higher in the group that received stents, even though their ability to walk did not improve as greatly as the group that received supervised exercise rehabilitation.The findings were published in the November issue of the journal Circulation. The researchers believe that more studies are necessary, although supervised exercise may be an effective treatment recommended for PAD patients with claudication.PAD is a condition in which plaque builds up in the arteries and affects blood flow, especially to the legs. It is estimated that between 10 and 12 million people suffer from PAD in the United States. One symptom of PAD is known as claudication, a painful cramping of the leg muscles that limits the patient's ability to walk. It affects nearly 2 million people who suffer from PAD, and results in a sedentary lifestyle and poor quality of life.Current U.S. guidelines for the treatment of claudication include pharmacotherapy, supervised exercise rehabilitation and lower extremity revascularization using stents.
