Due to his then-advanced age, Emperor Zhao allowed him to use a chariot as transportation while attending court sessions, instead of remaining on foot.
Thus, he was also known as "Prime Minister of the Chariot" (车丞相) or "Che Qianqiu" (车千秋; his entry in the Book of Han is listed under this name).
Shortly afterward, Tian became prime minister and was granted the title of "Marquess who Enriches the People" (富民候, Fu Min Hou).
Although Tian remained as prime minister until his death in 77 BC, no major political achievements were made by him.
Huo Guang, on the other hand, became the de facto ruler of China during the reign of Emperor Zhao of Han.
