HONG Kong schoolgirl Wong Ka-li led the territory's senior girls' team to a gold medal in the Thailand Open international gymnastics event in Bangkok yesterday. Wong, who represented Hong Kong in the 1990 Commonwealth Games in Auckland, New Zealand, won four gold medals in a gymnasium lacking air conditioning and with temperatures reaching 38 degrees Celsius. The 15-year-old Ti-I College student and her three senior teammates, Wut Fung-yin, Tang Fuk-kwan and Mok Chin-yee, won the gold medal in the team competition, from second-placed Taiwan, Indonesia, Thailand, the Philippines and Malaysia. Wong won the senior girls' individual all-round gold medal with a tally of 36.4 points for the four disciplines, taking first place on the vault (9.45) and the floor exercise (9.25) in the senior apparatus individual finals. Wut, who had won the all-round title two years ago in Thailand but is now struggling with a back injury, won a silver on the bars. The Hong Kong junior girls' team of Cheung Sin-man, Lam Ming-sze, Lau Sin-ting and Tang Wun-sze finished second in the team competition behind Taiwan but ahead of third-placed Thailand, Indonesia, Philippines and Malaysia. In the junior girls' individual all-round event, 12-year-old Cheung finished runner-up to Taiwan's Judy Ho. Cheung was first on the balance beam and third on the uneven bars in the individual apparatus, while Tang was second on the floor exercise.
