Introduction to the Coin Hall and Dance Hall: The "front hall" opposite the south gate is easily misunderstood, but it is actually the Coin Hall and Dance Hall. There are 2 coin halls on the east side and 3 dance halls on the west side. The imperial gifts for the Coin Hall's offerings, and the ceiling with a checkered ceiling are no different from those of the Dance Hall. On rainy days, the dance hall is used as a place for sacred music and dance music.
