The only current female Chinese hurdler to break 13 seconds over 100m, Wu clocked a personal-best 12.93 in 2013. She's already racked up an impressive medal count, taking golds at the 2012 Asian indoors, the 2013 East Asian Games and the 2013 National Games. She regained the national title last year and will be looking to lower her long-standing PB in Shanghai.
