The origin of Tibetan wedding banquets can't be traced back, but when Princess Wencheng and Songzan Gambu were about to get married, people were already singing congratulations at the wedding. This form is very similar to the Tibetan wedding banquet 18, which shows that the Tibetan wedding banquet 18 has a long history. The theory of eighteen Tibetan wedding banquets has not always spread in Tibetan inhabited areas as it is now, but has also appeared in Northeast China. However, after the Qing government quelled the war, people in some places were restricted to speak Tibetan, and naturally the eighteen theories on Tibetan wedding banquets were not allowed to appear in the local area, so the spread of the eighteen theories on Tibetan wedding banquets would become narrower and narrower.
Eighteen theories on Tibetan wedding banquets run through the whole wedding process, including offering sacrifices to gods, combing braids, combing combs, crying wedding songs, export songs, parents' instructions, horse talk, cushion talk, offering sacrifices to mountain gods, offering sacrifices to law gods, tea talk, wine talk and wedding talk. The whole process not only reflects parents' reluctance to marry their daughters, but also reflects everyone's blessing to the couple and their reverence for God. Moreover, in the whole wedding banquet, accompanied by song and dance performances and delicious food, Tibetan traditional culture was also displayed in such a grand wedding banquet.
However, with the changes of the times, many meaningful and valuable traditional cultures and literature have not been perfectly inherited, but gradually faded out of people's sight. The same is true of the eighteen theories on Tibetan wedding banquets. Because such a document only exists in people's mouths, and there is no relevant written record, the inheritance of the 18 th theory of wedding banquet has been seriously hindered, especially after the death of the older generation, such a traditional culture has not been accepted by young people, and we may never see this culture with unique language characteristics in the future development.
