BEIJING, Jan. 20 (Xinhuanet) --The air quality has worsened in the Chinese capital since Wednesday, triggering renewed discontent among residents.Without rainfall and wind to dispel pollutants, particulate matter has been accumulating in the air. Most monitoring stations measured PM 10 (particulate matter smaller than 10 micrograms) at higher than 300 micrograms a cubic meter.In southwestern Beijing's Fangshan district, the Liangxiang station recorded 516 micrograms of PM 10 a cubic meter, the highest reading of the day, according to the Beijing Municipal Environmental Monitoring Center.More than 150 micrograms a cubic meter is considered hazardous to health.Beijing has been shrouded by heavy smog off and on this winter, and the ongoing air concerns are wearing on residents particularly as they prepare to celebrate the Spring Festival holiday next week."I almost got choked by the smog when I stepped out of the office building on Wednesday," said Yang Yanli, 24, an accountant. "The smell is so terrible, as though I'm inhaling chunks of coal, that it has spoiled my holiday mood.""PM 10 intensity has been particularly high these days," said Wang Qiuxia, a researcher at the Green Beagle, a non-governmental organization based in Beijing.Unlike the smog that hit mostly the southern part of the capital on Jan 1, the smog in recent days has shrouded the entire city, according to the Beijing environmental protection bureau.Worse yet, it will linger until Saturday, when the wind will pick up and disperse it, the bureau predicted.The Chinese Center for Disease Control and Prevention suggests people stay at home to protect themselves from respiratory and heart problems triggered by heavy smog."The intensity of indoor pollutants is 30 to 60 percent lower than those outdoors during a hazy day," said Xu Dongqun, an officer with the environmental bureau. "I suggest people with respiratory problems put off traveling if the smog lingers."But many people said they had to brave the foul air to travel, especially migrants who are eager to reunite with their families during Spring Festival."No one likes to travel when the air is this bad, but do you have any choice when Spring Festival is coming?" asked Feng Xiao, a public servant at China's General Administration of Sport. The 24-year-old plans to travel by train from Beijing to her hometown in East China's Shandong province on Friday.

SHIJIAZHUANG, Oct. 16 (Xinhua) -- Chickens began being domesticated in China about 8,000 years ago, far earlier than in the rest of the world,according to a recent study on fossils uncovered in north China's Hebei Province.Archaeologists said they had unearthed 116 fossil specimens from 23 types of animals, including pig, dog, chicken, tortoise, fish, and clam, at the Cishan Site, a Neolithic village relic in the city of Wu'an.Several bone fragments were identified to be from domesticated chickens, said Qiao Dengyun, head of the Handan Municipal Institute of Cultural Relics and Archaeology."The chicken bones found at Cishan are slightly larger than wild jungle fowls, but smaller than that of a modern domesticated chicken," said Qiao.Qiao said the bone fossils date back to 6,000 BC, earlier than the oldest domesticated chicken previously discovered in India that dated back 4,000 years."Most of the bones were from cocks, indicating that ancient residents used the practice of killing cocks for their meat and raising hens for their eggs," said Qiao.The Cishan Site, which dates back 10,000 years, was first discovered in the 1970s. At the site, experts have found remnants of China's oldest cultivated millet as well as walnut shells, a discovery that challenged the popular belief that walnuts had been brought to China from what is now Xinjiang Uygur Autonomous Region and Central Asia.

BEIJING, Oct. 21 (Xinhua) -- China on Friday urged the European Union (EU) to recognize its full-market economy status at an early date and properly settle trade disputes amid the tumbling world economy."China hopes Belgium will exert its influence to push for an early recognizing of China's full-market economy status and remind the EU to be cautious on and restrain from using trade remedy measures," Vice Premier Wang Qishan told visiting Crown Prince Philippe of Belgium.Wang urged the 27-member bloc, also China's largest trade partner, to properly settle trade disputes with China during the talks at Diaoyutai State Guesthouse in downtown Beijing.Chinese Vice Premier Wang Qishan (R) shakes hands with Belgian Crown Prince Philippe in Beijing, capital of China, Oct. 21, 2011."China has contributed a lot to the world economy by recording a 9.4 percent growth in the first three quarters of this year while adjusting its economic structure and managing inflation expectations," Wang said.Prince Philippe, accompanied by a 450-member business delegation, is here to tap the Chinese market and seek investments from China, the world's top holder of foreign exchange reserves.During the 10-day trip, the delegation will visit the Chinese cities of Tianjin, Guangzhou, Shenzhen, Shanghai and Chongqing and is expected to sign about 40 contracts.Wang said China will expand two-way investment with Belgium, and enhance support to the two states' small and medium-sized enterprises via the China-Belgium direct equity investment fund.China-Belgium trade has continued to surge since the two states forged diplomatic ties in 1971, when the bilateral trade volume was only 20 million U.S. dollars, much less than the 22.1 billion U.S. dollar record in 2010."We could expand cooperation in two-way investment, trade, finance, chemical industry, environmental protection, logistics, and green economy," Wang said.
