What kind of person is Tian Dan in Historical Records?

Tian Dan is a distant relative of Tian's royal family in Qi State. During the reign of King Qi Min, Tian Dan was an official of George in Linzi. When Yan sent troops to attack Qi, the King of Qi fled and soon retreated to Jucheng. When the Yanjun attacked Qi all the way, Tian Dan also fled to Anping, letting relatives saw off the protruding part of the axle and put on iron hoops. Soon, the Yan army captured Anping, and the Qi people fled. Because the shaft head was damaged, they became prisoners of Yan. Only Tian Dan escaped and retreated to Jimo.
