What does the ancient Weizifang mean?

Refers to the palace. Selected Works of Wang Yanshou: "It is the secret hall of light, supplemented by purple." Zhang Zai's note: "Wei Zi, the Supreme Palace, refuses to be the capital." One of Tang Li Bai's Poems of Music in the Palace: "The little room is full of gold, and Yingying is in Wei Zi." Chen Ming Ruyuan's "Raiders of Jin Ping Mei Story Shooting": "Heming Shuangfeng is happy to come to the instrument, and the flowers are fragrant in three halls."

Later, Wei Zi Room was used to refer to gorgeous palaces, such as "Marriage and Pei Ziwei Room."
