Wang Hao and Wang Liqin, two of China’s top table tennis players, both saw the World Table Tennis Championships(世锦赛) as a chance to prove themselves. But there was only one trophy(奖杯) and Wang Hao, 25, won it last Tuesday in Yokohama(横滨), Japan.

Wang Hao, who won the men’s doubles title(对打) with Chen Qi last Monday, played with spirit to beat Wang Liqin.

Wang Hao said it was his mental toughness(心理韧性) that made the difference. “I was disappointed(失望) by my performances in past championships and the last two Olympic Games. But I have tried to pull myself together and prepared well. This is the result.”

Wang Hao said he has always understood the importance of physical training(体能训练) and technical skills(技巧). Now he knows the need for mental preparation as well. Having two Olympics silvers(银牌) had left him feeling bitter(辛苦的). The bitterness perhaps explains why he has not always played at his best in the past.

“I’ve come to understand that you can learn important lessons from failure,” he said. “Losing can build your character and make you a stronger player.” His next goal, or dream, is to win the gold medal at the London Olympics in 2012.

Liu Guoliang, head coach of China’s table tennis team, sang the praises of Wang Hao’s victory. “This is just the beginning of his rise,” said Liu. “it’s the confidence-booster(信心) he needs to make further progress.”
