More than 3,000 years ago, the King of Wu negotiated with the Shang Dynasty to establish the Western Zhou Dynasty, enfeoffment princes and shielding the royal family. However, after the reunification of Zhou Wuwang, many political ideals died before they were put into practice. The young king ascended the throne with the help of Zhou Gongdan. Duke Zhou gave full play to his talents, formulated a set of laws and regulations for the Zhou Dynasty, and managed the Zhou Dynasty in an orderly way. One day, Zhou Chengwang's younger brother Yu Shu played with Wang Cheng. Zhou Chengwang picked a plane tree leaf and gave it to his younger brother Yu Shu. He said casually, "I'll give it to you as a token!" " Uncle Yu was very happy to take the leaves, and then told the Duke of Zhou about it. Duke of Zhou thinks that what the son of heaven said is a promise. If it is true, it will be a serious problem, so I asked Zhou Chengwang. Zhou Chengwang said that he was just joking with his brother. After hearing this, Duke Zhou said seriously, "The Emperor of Heaven is not joking. It is recorded in the history books, praised by musicians and praised by literati. How can I talk casually? " After listening to Duke Zhou's point of view, Cheng Wang had to seal Yu Shu in the Tang Dynasty. Later, my son moved all his money to the Jinshui River and changed the Tang Dynasty into gold.
