Hu Biao, alias tinker, originally wanted to go to Laojiu with Hu Wei as a forward map, but he was captured by Qu Jianbo's team halfway and learned about the forward map. At that time, Qu Jianbo was upset because Hu Wei was easy to defend but difficult to attack, and there were few team members. Because he had a map in advance, he wanted to send someone to sneak into Hu Weishan. Yang Zirong accepted the task, entered Hu Weishan with an early map, and gained the initial trust of this mountain sculpture. He fled to Hu Weishan, but because Yang Zirong made full preparations and used his intelligence, he finally won the trust of Shan Diao. Yang Zirong took Hu Biao away and shot him.
