《旧唐书·列传·卷三十九》
王方庆又上告 ：法令明文规定 ：期丧，大功未葬，不参加朝贺，未终丧，不能参加宴会， 近来朝官不遵礼法，身有哀容，随同参加朝会，手舞足蹈，公然违背礼法，名教既亏，实在是玷污风化。
方庆又举： 令杖 期丧、大功未葬，不预朝贺；未终丧，不预宴会。 比来朝官不遵礼法，身有哀容，陪预朝会，手舞足蹈，公违宪章，名教既亏，实玷皇化。
Wang Fangqing also made a statement: "The law clearly stipulates: during the mourning period, the major achievements have not been buried, and you cannot participate in the court meeting. Before the mourning period is over, you cannot participate in the banquet. Recently, the court officials have not followed the etiquette, and they have a sad expression. Participate in the court meeting, dance and dance, openly violate the etiquette, the famous education is deficient, and it really tarnishes the social atmosphere.
