    "This is the best we have ever done," He Huixian, spokeswoman of Chinese delegation and deputy chef-de-mission said Sunday.

    "It is fantastic to have an opening day like that and we need to follow up with more victories.

    "But this lead could disappear at any time because the Olympic Games is so unpredictable. Please do not forget this is just the beginning," she said.

    China won four gold medals including the first gold of the Games out of a total of 13 on August 14, the first competition day. It takes the first spot on the medal standings with six medals plus another silver and bronze medals.

    Women's judoka Xian Dongmei from Guangdong Province added the fifth gold medal on women's under 52-kilo category with an overwhelming victory over Japan's 2003 World Championships bronze medallist Yuki Yokosawa yesterday before the paper was published.
