Tian Quan's original name was Chen Quan, and he was the son of Chen Ligong of the State of Chen in the Spring and Autumn Period. Chen Ligong's nephew Concubine Lin avenged the murder of his father and brother, killed Chen Ligong, and established himself as the Duke of Chen Zhuang, and Ren Tianquan as a doctor.
After the death of Duke Zhuang of Chen, his brother Duke Xuan of Chen succeeded to the throne. In his later years, Chen Xuangong killed the crown prince because he was friendly with Chen Quan and suspected that they would conspire to usurp the throne. Chen Quan, worried about his sin and himself, rushed to the Qi state with his family and family to avoid disaster.
After Chen arrived at Qi, Duke Huan of Qi accepted and appointed him. When Chen's descendants continued to the fifth generation, their strength increased greatly, winning the hearts and minds of the people and controlling the government. Until the eighth generation finally staged the scene of "Tian Shi Dai Qi".
Because the pronunciation of "Tian Chen" was similar in ancient times, after Chen's death, his descendants changed to the surname "Tian".
