Just play and enjoy it

Aug 8 is National Fitness Day in China. This is the day when the Beijing Olympics was declared open in 2008. Since 2009, this day has been marked to encourage people to play sports, exercise and honor the Olympic spirit.

Chinese hurdler Liu Xiang's perseverance and optimism make him a perfect role model for this year's National Fitness Day.

Liu crashed to the ground at the first hurdle in the 110-meter hurdle heats at the London Olympics on Aug 7. His Achilles tendon became his Achilles heel again at the Olympics. He had taken only a few steps and withdrawn from the Beijing Olympic Games because of injury.
