Chen Zhong Age: 21 Height: 1.80m Weight: 70kg Event: Over 67kg Defending champion Chen Zhong, who almost quit because of serious knee and ankle injuries during the past two years, never looked in danger. 'It's a wonderful feeling to come back to the Olympics and achieve victory again. I felt confident of winning. My mum was really worried that I would get hurt again after I injured my lower leg in a competition in 2002. I didn't want her to worry any more. She asked me to quit, but I still continued. I showed her on a website what kind of top competitors I would be facing. I told her, 'I must help my country, it is my duty' and my mother relented and gave her blessing. It was all I needed to give it my all.'
