It seems to be a kind of ridicule to talk about sleeping with Duke Zhou, but it is actually a very cultural statement, because in ancient times, Confucius, a Confucian sage, revered Duke Zhou very much and even dreamed of Duke Zhou in his dream. Ancient scholars, as followers of Confucianism, imitated Confucius and said that sleeping is to meet Duke Zhou. After a long time, this interesting statement with connotation spread among the people.
The core monument of life, Duke Zhou, is also known as Ji Dan, Zhou Gongdan, Shudan, Duke Zhou and so on. He is the son of a famous politician, strategist, thinker and educator, King Jichang of Zhou Wen. He has outstanding achievements, is the pioneer of Confucianism, and is also the most revered object of Confucius.
Because the Duke of Zhou read widely and dabbled in various fields, later generations even crowned The Book of duke of zhou with the name of Duke of Zhou. Although this book was not written by Duke Zhou, it can be seen that Duke Zhou's status and talent are very noble.
