《旧唐书·本纪·卷七》
近代以来，很少人遵循法度，王及公主，被曲折地致以私情，姑姑、叔父的尊贵，却对子、侄跪拜，违法背礼，令人感情悲哀。
近代以来，罕遵轨度，王及公主，曲致私情，姑叔之尊，拜于子侄，违法背礼，情用恻然。
In recent times, very few people have observed the rules. Princes and princesses have been given private banquets and titles, while aunts and uncles have knelt down to bow to their sons and nephews. This is unlawful and disrespectful, and it is very upsetting.
