He was the first yellow-man player in the world to defeat blacks in straight-line races, creating a record that even Caucasians have not done. He has participated in 48 competitions and won 36 gold medals in his career. Silver medal, 3 bronze medals, he is an athlete with many honors in the world record holder. His achievements are unprecedented, and it is difficult to come later. However, some people only remember that he retired twice. He won the Beijing Olympic Games in 2008. The recurrence of the bruises with the bruises has led to the retreat in the middle of the race. It is necessary to know that the injuries of the Achilles tendon are difficult to fully recover. This incident is extremely disappointing. Even the buzz, his foot injury and back injury were already serious during the 2012 London Olympics. But he did not dare to live up to everyone's expectations, still insisted on the competition, but fell at the moment of the rush out of the track, but still insisted on one foot to the end. In his lowest valley, he did not come out to say a few words to him. He is Liu Xiang, and we owe him an apology.
