Chinese jumper Huang Junkai and his team won the 9th #Shanghai International Double Dutch Contest. Huang broke his own world record with 140 single-foot jumps in 30 seconds — an average of 9.3 skips per second. In a #jumprope competition, not only is speed impressive, but the moves are also mind-blowing. Differing from traditional jump rope sport, freestyle jump rope combines the strengths of acrobatics, gymnastics, dance and martial arts, with greater artistic expressiveness and appeal. #FunChi
