According to the genealogy, after the Shang Dynasty was destroyed and the Zhou Dynasty was established, Shun's descendant "Chen Hu Gong Gui Man" was found, and he was sealed in Chen (now Huaiyang, Henan) to establish "Chen Guo". Hu Gongman spread to the tenth Sun Gui, and Chen was in civil strife. Gui, his son, was afraid of implicating himself, and fled to Qi State, taking the old country as his surname and renaming it Chen.

Chen is a descendant. Before Shun was born, Yao married his two daughters to Shun and let them live by Gui River. So the descendants of Shun are called Gui surname. In the early years of the Western Zhou Dynasty, after Zhou Wuwang destroyed the Shang Dynasty, he found Gui Man, a descendant at that time, married his eldest daughter, sealed him in Chen, and established the State of Chen, with its capital in Wanqiu (now Huaiyang, Henan).

He made Chen Guo prosperous for many years by selecting talents, promoting good and punishing evil, and making great efforts to govern. After Guiman's death, posthumous title was named Gong Hu, so he was also called Chen Hugong and Gong Hu. Later generations took the country as their surname, called Chen, and respected Chen as the ancestor.
