Introduction to Zhonghe Hall: It is a square hall with a single eave and a pointed roof. Each side is 21 meters, with three rooms each. There are 20 corridor columns, yellow glazed tiles with spires at the four corners, and a gilded crown in the middle. When the emperor went to the Hall of Supreme Harmony for business, he would rest here first and receive the worship of the cabinet, the Ministry of Rites, and the bodyguards. On the day before various important ceremonies, the emperor would also read memorials and congratulations here.
