Duke Zhou, namely Zhou Gongdan, was Zhou Chengwang's uncle, and he made great contributions to the establishment and perfection of the feudal system in the Zhou Dynasty.
Duke Zhou enjoys a lofty position in Confucian culture. Confucius said, "I no longer dream of Duke Zhou" is a metaphor for the loss of etiquette culture in the Zhou Dynasty. Duke Zhou is a frequent figure in Confucius' dreams. In China, where Confucianism has dominated the culture for a long time, Duke Zhou is inevitably directly associated with dreams. Dreams are often called "dreams of Duke Zhou" or "dreams of Duke Zhou".
I still have the original text of Duke of Zhou. Do you want it?
