WORLD wushu champion Leung Yat-ho is looking for revenge when he meets China's He Qiang at the East Asian Games in Shanghai, having lost to his former Guangdong teammate three times since the 1990 Asian Games. China-born Leung and He both learned nanquan - southern boxing - from the same master, Huang Jianggang, and there has been close rivalry between them for the last decade. Leung always held the edge during their teenage years and was the Guangdong provincial champion before he came to Hongkong five years ago at the age of 19. They renewed their rivalry at the 1990 Beijing Asiad and He won the gold medal with Leung settling for silver. He repeated the feat at the 1991 Penta-Wushu tournament but Leung showed his class by winning the World Championships the same year, in the absence of the Chinese ace. Their next meeting was at last year's Asian Championships, when He again emerged the victor. Leung, however, is determined to turn the tables on his former teammate before he retires from competition and is giving himself two years to fulfil his goal. ''I went back to Guangzhou for two months of intensive training early this year in preparation for the East Asian Games,'' said movie stuntman Leung. ''My fitness has never been better but I'm still a bit worried I may not be able to finish my performance as strongly as He Qiang, who can maintain full power in his every movement even towards the end of his routine. ''If I can't beat him this time, I'm determined to do it at next year's Asian Games because I've already planned to stop work for six months and train full-time for Hiroshima.''
