What are the four etiquette of Tujia nationality?

In the long feudal era, Tujia people gradually formed multi-level etiquette in the marriage system, which was very complicated and grand. It is a complete etiquette process, but in the whole etiquette process, the most important thing is the coronation ceremony of men and women held on the wedding day and a series of other etiquette activities. Such as "proofing", that is, the matchmaker matches men and women to meet for the first time, commonly known as "looking at appearance", and then formally proposes after both parties are satisfied. "Propose marriage", after proofing, the man formally invited the matchmaker to propose marriage to the woman's house. "Begging for Red Geng", commonly known as "matching eight characters", was written on the "Red Geng Sticker" when the man entrusted the matchmaker to obtain the date of birth of the woman, and asked the local teacher or fortune teller to infer according to the five elements of Yin and Yang to see if it was consistent or mutually acceptable. "Engagement", commonly known as "inserting incense", is a "match made in heaven". Both men and women hold a banquet on an auspicious day and invite their relatives to formally engage. In fact, it is to make this marriage public and gain social recognition.
