《贞观政要·卷七·论礼乐》
从今以后，让天下人都要懂得嫁娶的规矩，务必合乎礼法，按照朝廷的礼仪办事，才符合我的心意。 
自今以后，明加告示，使识嫁娶之序，务合礼典，称朕意焉。 
From now on, let everyone in the country understand the rules of marriage, that they must be in accordance with propriety and the law, and that they must comply with the etiquette of the court in order to be in accordance with my wishes.
