《礼记·曲礼上》
大夫级别的官员，到了七十岁就可以把所掌管的事情交还君主而告老。如果告老未得允许，那么君主一定要赐给大夫几和杖，在本国因公外出，可以有妇人陪从。
大夫七十而致事。若不得谢，则必赐之几杖，行役以妇人。
Officials of the doctor's rank, when they reach the age of seventy, can hand over the affairs they are in charge of to the monarch and retire. If the request for retirement is not granted, then the monarch must give the doctor a few and a cane, and when he goes out on official business in this country, he can be accompanied by a woman.
