It is said in ancient times that the general trend of the world is that if it has been divided for a long time, it must be united, and if it has been united for a long time, it must be divided. At the end of the Zhou Dynasty, the seven kingdoms competed for supremacy, and later Qin swept Liuhe and unified the four seas; after the destruction of Qin, Chu and Han confronted each other and were finally unified under the Han; at the end of the Eastern Han Dynasty, they were further divided into three kingdoms and merged into Jin. After the Jin Dynasty, it was divided into north and south, and then unified again by the Sui Dynasty. The Tang Dynasty succeeded the Sui Dynasty, and the road was blue and blue. It arose in Zhenguan, and the chaos began in Xuanzong. At the end of the Tang Dynasty, the feudal vassals and towns were separated, which eventually led to the collapse of the country and the beginning of troubled times. By chance, Wen Di traveled to the Five Dynasties and Ten Kingdoms, met young Zhao Kuangyin, and such a story happened.
