The architecture of the Forbidden City in Beijing is divided into two parts: the outer court and the inner court. The center of the outer court is the Hall of Supreme Harmony, the Hall of Zhonghe and the Hall of Baohe, which are collectively called the three halls, and are the places where the country holds ceremonies. The left and right wings of the three main halls are supplemented by two groups of buildings: Wenhua Hall and Wuying Hall. The center of the Forbidden City is Gan Qing Palace, Jiaotai Palace and Kunning Palace, collectively referred to as the last three palaces, which are the main palaces where emperors and empresses live. Followed by the imperial garden. On both sides of the last three palaces, there are six palaces in the east and west, which are places where empresses live and rest. On the east side of the East Sixth Palace are Buddhist buildings such as the Heavenly Palace, and on the west side of the West Sixth Palace are Buddhist buildings such as the Zhongzheng Hall. In addition to the outer court and the inner court, there are two buildings: Waidong Road and Waixi Road.
