Overseas training program pays off

Sending its best abroad, the Chinese swimming team's overseas training programs paid off as the squad only trailed the dominant United States on the final medal table at the Shanghai World Championships.

China's four gold medalists all trained overseas, which obviously helped them to success in Shanghai.

New sensation Sun Yang was sent to train in Australia with Olympic medalist Grant Hackett's mentor, Dennis Cotterell, for two months earlier this year. He went on to break Hackett's 1,500m freestyle world record in Shanghai. The record had stood for 10 years, including during the super-fast hi-tech suit era, until Sun smashed it on Sunday.
