《宋书·志·卷十五》
大学博士顾雅议论说： 现今既然都用士礼，就应该同于服齐衰和执削杖，布带白麻布鞋，服丧一年，礼毕后，行心丧礼三年。 
太学博士顾雅议： 今既咸用士礼，便宜同齐衰削杖，布带疏履，期，礼毕，心丧三年。 
University doctoral degree recipient Gu Ya said: Now that all people use commoner's ritual, it should be the same as wearing mourning clothes of Qi Zhao, holding plain white wooden canes, wearing white hemp cloth shoes, observing one-year mourning period, and performing xin funeral after the end of the mourning period for three years.
