First, the boxing match is very fierce and dangerous. In the competition between Joanna and Zhang Weili, the intensity of the competition is very high. In the end, Zhang Weili won by a narrow margin. Although it is a women's competition, Zhang Weili and Joanna are both very strong, so they are almost boxing to the flesh, and boxing is powerful. The bones of the face are very fragile, but in order to score more points, boxers usually attack the opponent's head. When the face and head are frequently hit by the opponent's heavy punches, the bones can't bear it.
Joanna's facial orthopedic fracture is actually quite minor in boxing. Before a boxing match, athletes need to sign a voluntary letter to prevent being knocked down by a boxing match. Some powerful boxers are likely to make their opponents faint with one punch, so the boxing match is too fierce and dangerous.
Second, Joanna shouted before the game. Zhang Weili is eager to win. I have to say that it is precisely because Joanna looked down on China athletes before the game and has been cheering for Zhang Weili, so Zhang Weili and all China are very eager for this victory and hope to see Zhang Weili defend the title. Therefore, in this game, Zhang Weili was more active and intense than usual, and basically showed no pity. So Joanna's face began to deform when she encountered several punches, and the swelling was more severe and the deformation was more obvious during the competition, so it needed plastic surgery.
