China's first and only Grand Slam winner Li Na recently announced her retirement due to a serious knee injury.

"Tennis is what I love, so I will try my best to help more children play," 32-year-old Li said at a press conference in Beijing on September 21. "I won't be a coach of one or two particular players, but work more on the basic training of children at their starting point." She plans to open a tennis academy after leavingcompetition.

Li, born in Wuhan, central China's Hubei Province, is the most successful tennis player in China. She began playing at the age of 6 and became a professional in 1999. In 2011, she became the first Asian to win a Grand Slam title at the French Open. Experiencing ups and downs in 2012 and 2013, Li found the top of her game again this year, bagging a second Grand Slam title in the Australian Open in January.
