《宋书·志·卷十五》
皇太妃对皇上不服丧，故所以该依情理为各藩王及君主对皇上应行期服的反服，皇太妃及王妃三夫人九嫔各行致哀之礼。
太妃于国亲无服，故宜缘情为诸王公主于至尊是期服者反，其太妃王妃三夫人九嫔各举哀。
Since the Imperial Grand Concubine did not observe the mourning for the Emperor, all the feudal princes and monarchs should follow the mourning rituals based on reason, and conduct the counter mourning. The Imperial Grand Concubine, the Princess Consort, the Three Madams and the Nine Concubines should all perform the mourning rituals.
