《史记·七十列传·田叔列传》
田仁认为太子和皇帝是骨肉之亲，不想卷进他们父子之间的冲突，就离开城门到各个陵寝去，使太子得以逃出城门。
司直以为太子骨肉之亲，父子之间不甚欲近，去之诸陵过。
Tian Ren believed that the prince and the emperor were related by blood, and did not want to get involved in the conflict between their father and son, so he left the city gate to go to the various mausoleums, allowing the prince to escape the city gate.
