What is the relationship between Duke Zhou and Duke Meng?

Duke Zhou, as we usually call him, is actually his father, Ji Chang.

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 "the dream of the Duke of Zhou" or "the dream of the Duke of Zhou".

In those days, Zhou Wang indulged himself and killed his ministers, and Ji Kang couldn't help crying. But Zhou Wang knew he was locked up, and the worst thing was to kill Bo Yikao, the son of King Wen, and let him drink broth. Ji Chang endured humiliation and studied the Book of Changes in prison, and finally wrote the Book of Changes. King Wen is the originator of fortune telling!

In Cao Cao's poem "The Duke of Zhou vomits food, and the world returns to the heart", the Duke of Zhou actually refers to Zhou Gongdan, the fourth son of King Jichang of Zhou Wen and the younger brother of Ji Fa of Zhou Wuwang. He has twice assisted Zhou Wuwang in its eastward expedition to Zhou Wang and had fun. Because of its fief in Zhou, Jue is the main, so it is called Duke of Zhou. Duke Zhou was an outstanding politician, strategist, thinker and educator in the early years of the Western Zhou Dynasty, and was honored as a "sage of Yuan Dynasty" and a pioneer of Confucianism.

Judging from the historical documents handed down from generation to generation, Duke Zhou's achievements were mainly military. Under the unstable situation in the Zhou Dynasty, Duke Zhou defeated Yin for the second time, unified the East and established a military center centered on Cheng Zhou. Politically, patriarchal clan system and enfeoffment system were established; Culturally, the system of rites and music is the epitome of Zhou Li. Duke Zhou was highly respected by Confucius and regarded as a saint by Confucianism. Duke Zhou's thoughts played a fundamental role in the formation of Confucianism, which was called Duke Zhou and Confucius in the Han Dynasty.
