Theater introduction: In front of the ancestral hall, there is a square pool. Across the pool is a stage. The front entrance of the stage extends into the water. There are four stone pillars in the water, with cornices and brackets and painted beams. There is a fan-shaped ink painting hanging on the wall behind the stage, and a couplet hanging on both sides: "The bright moon hangs in the mirror, and the pine wind sings the strings of clothes." Imagine that the sound of silk and bamboo music is coming from the water, and the lingering sound will definitely give you the feeling that "this music should only exist in heaven".
