In history, everyone knows Zhao Yun, one of the Five Tiger Generals, and Zhang Xiu, a god with a gun, but do you know their teachers? When Zhao Yun was young, he liked to dance with guns and sticks, but at that time there were no martial arts schools at all, and even if there were any, there was no money to attend one. Occasionally one day, when Zhao Yun was waving a stick at home, he was seen by an old man passing by. The old man was not gorgeously dressed at the time. He walked over and performed a few tricks. Unexpectedly, Zhao Yun learned it after just one look. So he accepted Zhao Yun as his disciple, and eventually became the Five Tiger General of the Three Kingdoms period, Changshan Zhao Zilong.
