First, after ZhangJike won the game, all the billboards were smashed.

When ZhangJike won the World Cup, he was really excited, so it was because he was so excited that ZhangJike smashed all the billboards. ZhangJike's behavior, in Liu's view, is a disgrace to China athletes and also damages the image of China athletes, so even if ZhangJike wins the competition, Liu Ye denounces ZhangJike.

Second, we can understand ZhangJike's excitement, but it is really inappropriate to destroy public property.

Every athlete will be very excited after winning the championship and the competition. ZhangJike was understandably excited to win the World Cup. But because of excitement, all the billboards under the stage were broken and public property was destroyed. This behavior is really inappropriate.

Third, ZhangJike's personality has always been more publicity, so he would do such a thing.

ZhangJike's personality has always been relatively high-profile, and he will be very excited after winning the game. It is because of his character that he will do such a thing after winning the game. I hope ZhangJike can realize his mistake and abide by the code of conduct of the stadium.
