Later, the palace where concubines lived was called the West Palace. The East Palace is the palace where the prince lives and is also used to refer to the prince. It was not until the late Qing Dynasty that the names of Dong Taihou and Empress Dowager appeared in the history of China. East, west upward, the ancients headed by the east, followed by the west. Therefore, the ancestral temple, with the East Palace as the largest, dedicated to ancestral tablets, should be built on the east side of the palace.
The correlation is as follows
In the Yi-ology, divination in the Eight Diagrams represents the East, the eldest son in human relations, and the East is the most suitable place for the eldest son to live. Palace geomantic omen will naturally follow this concept. Most of the ancient governors were the eldest sons, and the East Palace was specially built in the east and assigned to the governors. I hope that the members of the world's first family are in their proper places and * * * let the world be together. The natural prince is also known as the "Prince of the East Palace".
In folklore, there are always queens living in the East Palace and concubines who object to the queen living in the West Palace, but this is just a folklore, which is not true. Xigong is usually recorded in the history books as the residence of the emperor's father.
