《资治通鉴·汉纪·汉纪十四》
他为人沉静仔细，每次出入宫廷、下殿门，止步和前进都有一定的地方，郎官、仆射们在暗中观察、默记，发现他尺寸不差。
为人沈静详审，每出入、下殿门，止进有常处，郎、仆射窃识视之，不失尺寸。
He was a quiet and careful person. Every time he entered or left the palace or passed through the palace gate, he stepped forward and stopped at a specific place. The Langguan and Pushe officials observed and memorized his actions. They found that he never made any errors.
