Wu finds herself, with no time to spare

China's Olympic champion, Wu Jingyu, has rediscovered her form just in time to defend her taekwondo title at the London Games.

Wu, the Beijing Olympics' flyweight (49kg) gold medalist, hit a career slump after home glory due to fatigue and a lack of motivation.

The once-unbeatable Wu started to lose major battles in 2009, crashing out of the National Games and the World Championships before the finals.
