《元史·本纪·卷二十八》
初四，祭享太庙，因国哀迎香免去奏乐，因修庙工程未完成，妨碍陈设宫悬，只采用登歌。
戊辰，享太庙，以国哀迎香去乐，修庙工役未毕，妨陈宫悬，止用登歌。
On the 4th, offerings were made to the Imperial Ancestral Temple. Because of the national mourning, the music for welcoming the incense was dispensed with. The offering of palace hangings was also prevented due to the ongoing temple repairs, and only hymn singing was used instead.
