Chen Cheng, a modern social animal, accidentally possessed "happy", his ancestor in the late Qin Dynasty. With the help of historical prophets, he gave advice to Liu Bang to rule the world. He was granted the title of Guandu Marquis and made a covenant that "Chen will not betray Liu and Liu will not abandon Chen". He avoided trouble, stabilized the court, and laid the foundation for the Chen family. Since then, the descendants of the Chen family have inherited the family tradition from generation to generation. They have repeatedly made outstanding achievements in Wen, Jingwu and other dynasties, avoiding party disputes and spreading branches, and based themselves on military merit, strategy and cultural inheritance. After hundreds of years of ups and downs, the Chen family has always adhered to a low-key and pragmatic approach, and finally became a thousand-year-old family that does not involve in the struggle for imperial power but affects the direction of the world. The family's glory continues.
