What are the main buildings of the Forbidden City in Beijing?

The main buildings of the Forbidden City in Beijing are divided into two parts: the former dynasty and the Forbidden City. Hall of Supreme Harmony, Hall of Zhonghe and Hall of Baohe are the centers of all previous dynasties. Behind the three halls is the Forbidden City, including Gan Qing Palace, Jiaotai Palace, Kunning Palace and Dongxi Palace. Gan Qing Palace is the emperor's bedroom, followed by Kunning Palace and the queen's bedroom. The small square hall between the two palaces is Jiaotai Hall. These three halls are collectively called "the last three palaces". In the imperial garden behind the Forbidden City, pavilions, green willows and pines, dotted with exotic flowers and stones, are full of interest, and have some vitality and fun in a rigorous court atmosphere. The whole building complex is symmetrically arranged according to the central axis, with distinct levels and prominent main body. From a distance, heavy yellow glazed tiles, crimson walls, finely carved white marble railings and colorful beam-column decorations make people feel grand and colorful.
