There are Sichuan Opera, Anhui Opera, Han Opera, xiang opera Opera, Yunnan Opera, Hebei Bangzi Opera, Qin Opera, Henan Opera, Yuediao Opera, Quju Opera and so on. The story tells that after the death of Ming Taizu Qin Long, Prince Zhu Yijun (later Emperor Wanli) was young (10 years old), and Li Yanfei (known as Li Guifei in history, and Zhu Yijun was promoted to Li Taihou after becoming emperor) listened to politics. His father Li Liang deceived Li Fei in an attempt to usurp the throne. He appointed King Xu Zhao Yan (prototype is "Ming History" Xu Jie) and Ministry of War Assistant Minister Bai Yang (prototype is Ministry of War Shangshu Wang Chonggu) to sternly persuade Li Fei in Longfeng Pavilion, but Li Fei was stubborn, and the monarch and the minister argued and broke up in discord.
