The Yi ethnic group's wedding customs and rituals, represented by Meigu County in the heart of Liangshan, have become a rare cultural landscape with their ancient and unique customs. According to the Yi epic "Le'otei", the Yi ancestors had experienced a matriarchal society where "they only knew their mothers but not their fathers". In order to find his father, Shi'er'ote went through hardships. Under the guidance of Zini Shise, he married and entered the patriarchal era where children could see their fathers. The Yi ethnic group's wedding customs are extremely rich and unique. Whether it is marriage selection, wedding pranks, diet and water conservation, water splashing, carrying the bride on the back, or ancient traditions such as Saikezhi and crying at marriage, they all have a wide range of influences and unique values. The conclusion of a Yi marriage is not only an individual behavior of a family, but also a collective behavior involving the entire family, in-laws, neighbors, etc. It is also a process of national cultural dissemination and acceptance. The wedding process is a grand display and interpretation of Yi culture. Whether it is the oral recitation of "Kesi", "Kezhi", "Zuo" and other ancient and modern, or the beautiful and melodious "Niuniuhuo" poetry singing, or the tradition of crying to express separation and resistance to arranged marriage, or the entertainment and competitive water splashing, wrestling, "Shuque", beating relatives, wedding ceremonies, or the customs of snatching dog food, not staying at the husband's house, and grabbing on the night of marriage consummation, they all have profound historical and cultural connotations, express unique folk customs, and have multiple cultural values. With the changes in production and lifestyle, typical and complete Yi wedding forms are becoming less and less. It is imperative to protect and rescue this ancient folk custom.
