Introduction to the dome: The top of the hall is a large dome with a diameter of 9.5 meters, and there are small domes at each corner. The large and small domes are all green, and the tops are decorated with treasure vases. The crescent moon on the large dome is 22 meters away from the surface. Between the bottom of the large dome and the square pillars in the hall is a cylindrical drum base with 24 skylights. In addition, there are 6 large windows on the north and south sides of the hall, which increases the brightness of the light in the hall.
