He plays "The Leopard", and when he sees Miss Yin, he can leap down from the high table over the heads of the little leopards in thick-soled boots. The skill of playing the fork also absorbed many martial arts tricks, such as shaking the fork, holding the moon, wearing jade and so on, and created many novel skills. This play is also his best work in the world. Later, Wu Sheng, Zhou Ruian and others performed "The Leopard", which was patriarchal to him. At that time, he and Yan Lanqiu (Nine Gusts) played a lot of martial arts, and both of them were famous for their popularity and fancy, and they could be called diamond cut diamond, which made the people who watched the play feel particularly exciting and enjoyable.
