《新唐书·列传·卷三十四》
礼仪家说明道： 王后不参与祭祀天地五岳，所以没有祭祀天地五岳的礼服。 
礼家说曰： 后不助祭天地五岳，故无具服。 
The official in charge of Zhou's Etiquette explained: The queen did not participate in worshipping the heaven, the earth and the five mountains, so she did not have ritual dresses for worshipping the heaven, the earth and the five mountains.
