Located in Xieheyan Street, Xuanwu District, Beijing, south of the Hepingmen Gate, Zhengyiqi Theater Building is one of the most famous theaters of Beijing Peking Opera. It is also the oldest well-preserved wooden theater in China. Zhengyi Temple Theater Building was originally built by Zhejiang merchants as a silver hall theater. When Emperor Xuanzong of the Tang Dynasty, there was a woman, Jiang Cailin, who was favored by Emperor Minghuang of the Tang Dynasty, because she was good at light make-up and elegant clothes, and admired plum blossoms, so she was named "Mei Fei", and then Yang Yuhuan entered the palace, and she used all her tricks to make Mei Fei lose her status.
