Liu Xiang, China's 110m-hurdle world champion and Olympic gold medal winner clears a hurdle during a training session in Shanghai, east China, on June 30, 2009. As Sun Haiping, Liu's coach said during yesterday's press conference, the hurdler is recovering well from his ankle injury but he is not a hundred percent fit for competition. The former 110m hurdles record holder pulled out of the Beijing Olympics last year due to an injury and has not been in competition since then. [Xinhua]
