There are six palaces in the "Three Palaces", namely Ren Jing Palace, Chenggan Palace, Zhongcui Palace, Jingyang Palace, Yonghe Palace and Yan Xi Palace. The "Six Palaces on West Road" are Yongshou Palace, Yikun Palace, Palace of Gathered Elegance, Xianfu Palace, Changchun Palace and Taiji Palace (Qixiang Palace). Because all palaces are quadrangular buildings, they are called "East Sixth Courtyard" and "West Sixth Courtyard".
The Forbidden City is the imperial palace of Ming and Qing Dynasties. Judging from the architectural layout, it is in accordance with the ancient regulations of "front facing and rear sleeping", and the outer facing is "the big interior is the official residence" and the inner moving is the so-called "three palaces and six courtyards". The queen is in the center (Kunning Palace). There are six palaces in the east and six palaces in the west (the buildings in the palace are mostly organized in units of nine, so six instead of nine is used here, which obviously conforms to the saying that "six palaces are built in the back").
Extended data:
The so-called three palaces in the folk generally refer to the middle palace and the east and west palaces where empresses live. In fact, this is the system after the Ming and Qing Dynasties. The three palaces originally referred to the three palaces of the emperor, empress dowager and empress, or the three palaces of the empress dowager, empress dowager and empress.
The son of heaven and his wife live in the sixth house. "The Book of Rites" said: "The queen has six palaces, and the princes' wives have three palaces." "Zhou Li? "The Palace Massacre" said: "The Queen is handsome in the Sixth Hospital." Zheng Xuan noted the six palaces: "One is the official bedroom, the other is the Yan bedroom, a total of six palaces." The sixth palace is the residence of the queen, so it is often used to address the queen, just as the later generations used the middle palace to address the queen.
With the establishment of feudal society and the demise of princes, the meaning of the three palaces has changed. In the Han Dynasty, the emperor, empress dowager and empress were collectively called the Three Palaces, also known as the Empress Dowager, Empress Dowager and Empress Dowager. In Tang Dynasty, Mu Zongshi also called two empresses and empresses three palaces.
