The Fifth National Intercity Games opened in Changsha City, Hunan Province on Saturday. Thousands of under-23 athletes from more than 78 cities, special economic zones and municipalities are taking part in the 10-day mega event. Hong Kong has sent 89 athletes to compete in 13 sports at the four yearly competition, seen as a valuable occasion to identify talent and build team spirit ahead of next year's Olympics. The SAR competes in swimming, diving, athletics, badminton, gymnastics, shooting, table tennis, baseball, cycling, fencing, rowing, windsurfing, tennis and wushu. The Hong Kong squad include many talented young athletes still in secondary school or university, such as Yu Hoi-ping, Chung Kwok-leung and Chan Wing-suet (swimming), and Casey Tse Ka-chun and Yu kwok-sze (table tennis). 'As a premier national sporting event, the Games aim to identify and nurture talent, to build up the national teams for the 2004 and 2008 Olympic Games and to enhance sports development in various cities,'' reads a statement on the website of the Leisure and Cultural Services Department. 'To ensure that all players are of the highest clibre, the organising committee has gone through a strict selection process. The athletes were identified from the recommendation list of the national sports associations. They all have rich competition experience,'' says the statement. Four years ago, the SAR sent a 68-member delegation for its National City Games debut in Xian. Local sprinter To Wai-lok won a silver medal in the men's 100 metres, and swimmer Fu Wing took bronze in the men's 50m freestyle. Cyclist Lam Kai-chun has already clinched Hong Kong's first medal at this year's Games. He won the men's individual road race in Taiyuan, Shanxi, earlier this month. Lam's gold added to the bronze won by Chan Wai-man in women's mistral windsurfing recently. The National Intercity Games of 1988, 1991 and 1995 were held in Jinan, Tangshan and Nanjing respectively. .
