According to relevant documents, "Chen surnamed Yao was sealed in Luoyang before his name was published." Dajie was the third son of Emperor Yao, and his descendants were also called Dajie in the late Western Zhou Dynasty. When he led the army to promote Jin and conquer Rong, he made great contributions to the restoration of Zhou Dynasty. Therefore, after Zhou Pingwang moved the capital in the Eastern Zhou Dynasty, he was given a land to change the soil, taking the feudal city as his surname and calling it "reform". This surname "Chen" who lives in the Central Plains is called "Chen". For example, Chen Rong, the author of the novel Man to Middle Age, and Chen Long, the Olympic champion.
According to another document, "Chen was born in Jizong, descended from Zhou royal family, and his ancestral home was Chengzhou (now Luoyang, Henan). His fourteenth son, whose lineage was passed on to Ji Gong, was named "Chen". The country was lost because of conquest, and the descendants took the country as their surname. " This tribe named "Chen" moved from one place to another, probably influenced by dialects in the process of migration, and the surname "Chen" was gradually changed to "shèn".
