The emperor is heaven, the queen is earth, the emperor is dry, the queen is dry, the queen is the only one in the world, the queen's bedding palace is taken from the moral scripture, "the earth has a Ning" this sentence, so the name of the Suining Palace, the same thing "the heaven has a clear", the emperor bedding palace name dry Qing Palace. Therefore, the Suining Palace and the Ganqing Palace are the bedding palaces of the queen and the emperor respectively. The Ganqing Palace represents positive, and the Suining Palace represents negative, to indicate the combination of yin and yang, and the world combines with the meaning of the earth.
