Duke Zhou, who is he? Can you be more specific? Thank you.

Zhou Chengwang's uncle Zhou Gongdan made great contributions to the establishment 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", which 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". The Duke of Zhou in The Duke of Zhou refers to Zhou Gongdan.
