How did the traditional custom of Tujia people crying for marriage come from?

The content of "crying marriage" of Tujia girls in western Hunan has been passed down from generation to generation, and some "crying marriage mothers" have been accumulated and pondered, thus forming some similar oral "notebooks"-an amazing folk lyric poem "Crying Marriage Song". Several "notebooks" existing in Mawang Township, Baojing County, Purong Township, Yongshun County and Pojiao Township, Longshan County are relatively complete and have their own characteristics. In these places, there are many famous old "weeping brides", among whom Ding Xiangui, Tian Cuilian and others also participated in the filming in the 1980s. If you travel to Mengdonghe Scenic Area, you may see the "crying marriage" performance of their disciples and grandchildren in Wangcun Ancient Town.

According to the three songs "Books" published in 1950s, 1970s and 1980s, this long folk poem can be divided into more than one 10, with thousands of lines, such as crying parents, crying brothers and sisters, crying matchmaker, crying dowry, crying ancestors and crying sedan chair.
