China's top tennis official has called for reform to the country's state-run sports system after the success of Li Na at the French Open.
Li Na is the first Asian tennis player to win a singles Grand Slam event.
The director of China's tennis programme says more athletes should follow Li Na's lead and break away from the country's sports system.
Sun Jinfang has told the Xinhua news agency there must be innovation in the centralised training system.
In 2008, Li opted out of the state system and set up her own training team.
