Introduction to the Theater: The Theater, also known as the Song Tower, was used for festivals, sacrifices, wishes, and birthday celebrations in the old days. The theater floor is three rooms wide and divided into front and back parts. The front stage is a "music bed" used for formal performances, and the backstage is a "theater room" dedicated to actors' makeup. During the Qing Dynasty, the 13th day of the first lunar month, the 13th day of the fifth lunar month, and the 13th day of the ninth lunar month were dedicated to perform performances in honor of Emperor Guan Sheng.
