Duke Zhou is a real person.
Zhou Gongdan is the son of Zhou Wenwang and the younger brother of Zhou Wuwang. He helped Zhou Wuwang destroy the Shang and Zhou Dynasties. After Zhou Wuwang's death, Zhou Chengwang was a baby. He helped Wang Cheng manage the world.
The Zhou Dynasty sealed the land to the Duke of Zhou, who sent his son Boqin to manage it. When Duke Zhou left, he warned Boqin: "I am the son of King Wen, my brother, and my uncle who became a king, and I have a high status in front of the world. But I often stop to take a shower, spit out the food in my mouth many times, and hurry out to meet the visiting guests. That's why I'm afraid of chilling everyone. I hope you will not be proud of your position when you arrive in Shandong. "
Duke Zhou's theory of sleeping god is false. Confucius once said, "I am weak!" For a long time, I stopped dreaming about Duke Zhou! "Later generations often call sleeping the dream of the duke of Zhou.
