Athletes carry torch for the future

Chinese athletes have cast off the shadow of star hurdler Liu Xiang's retirement to restate the country's challenge to world powers in track and field.

China saw breakthrough performances at the World Athletics Championships, which ended in Beijing on Sunday evening.

The sad memory of Liu withdrawing from the 110-meter hurdles final at the Beijing Olympics in 2008 was erased in the Bird's Nest stadium on Saturday when China took the silver medal in the men's 4x100m relay.
