《贞观政要·卷七·论礼乐》
贞观四年，唐太宗对侍臣说： 我听说，京城的百姓在为父母服丧期间，有的人听信巫师的妖言，在辰日这天不哭，他们谢绝别人的哀悼慰问，拘泥于禁忌不允许悲伤，这是伤风败俗、违背人情事理的做法。
贞观四年，太宗谓侍臣曰： 经闻京城士庶居父母丧者，乃有信巫书之言，辰日不哭，以此辞于吊问，拘忌辍哀，败俗伤风，极乖人理。
In the fourth year of Zhenguan, Tang Taizong said to his officials: I heard that the people in the capital mourned for their parents, and some listened to the priests' sorcery, and would not cry on the day of Chen, and refused to accept condolences from others to express their condolences. , It is against human nature to stick to taboos and not allow sadness.
