 Wu Dajing became the first Chinese male short track speed skating Olympic champion by breaking the world record at the 500 metre event.Since Chinese athletes are more likely to compete in more than one event in the sport of diving, gymnastics, table tennis, swimming, and more likely to compete in several Olympic games in the sport of shooting, most multiple medalists listed in the following three tables come from these five sports.Among other six sports that may produce top multiple medalists, China may have breakthroughs in fencing and cycling, while chances are slim in athletics, canoeing, rowing and equestrian.
