     BEIJING,March 1 (Reuters)-China hailed its best ever Winter Olympicson Monday,

gold,two silver and four bronze medals in Vancouver.

     Only eight years after skater Yang Yang (A) won the country's first Winter gold at Salt

Lake City,a sweep of the women's short track speed skating and a first figure skating title

helped China to joint seventh place in the medals table.

     "Gold Standard" read the banner headline on the front page China Daily,while the

People's Daily led its sports page with "Vancouver historical breakthrough".

     "We have made an important breakthrough at these Games," Xiao Tian,deputy chefde

mission of China's largest ever Winter Games delegation,told the Xinhua news agency.

     "Actually the fivegold finish was within my expectation before we set off for the Games,

but I couldn't say that at that time because I would not want to put any pressure on the

athletes.Now I can speak out."

     Xiao was quick to return to the earlier subject of conversation to pessimistic (悲观) type,

Beijing Olympics.

of China's winter sports," he said.

     "It's impossible for us to reach the same level as we have done in Summer sports,but we

will try to minimize the gap as much as we can."

     Xiao said that progress would come not through a vast expansion of the Winter sports

programme but by using the best coaches,wherever they came from,and technology.
