《三国志·魏书·桓二陈徐卫卢传》
曹爽诏令说： 过去干木辞官修养，都能靠大义威压强大的秦国；留侯休养生息，也没有忘记楚国的事。
诏曰： 昔干木偃息，义压强秦；留侯颐神，不忘楚事。
Cao Shuang decreed and said: Previously, Gan Mu resigned from his office and cultivated himself. He was able to rely on righteousness to intimidate the powerful Qin Kingdom; Liu Hou took a break and recuperated, but he never forgot about Chu Kingdom.
