The Mythological System and Cultural Integration of Tu Ethnic Wedding Songs

婚礼歌是土族婚礼中不可或缺的重要组成部分，其主题往往与土族神话有密不可分的关系，从创世之初到婚姻之由再到道德准绳，婚礼歌中涵盖着众多神话文本，其本身也是土族神话传承的重要载体之一。婚礼歌为这个只有语言而无文字的民族保留了诸多珍贵的神话资料，使其得以代代相传，不致流失，也突出表现了土族先民的价值观与道德准则，在河湟流域这样多民族聚居的区域，土族婚礼歌神话融合了诸多其他民族的神话母题，同时又不失自己的创造性，具有鲜明的特色，在婚礼歌的传唱过程中，土族神话得以焕发出新的生机，在当代社会依然有着不可忽视的文化价值。The wedding song is an indispensable part of the Tu wedding, and its theme is often closely related to the myth of the Tu nationality. From the beginning of the creation to the cause of marriage and then to the moral standards, the wedding song covers many myth texts, and it is also one of the important carriers of the inheritance of the myth of the Tu nationality. The wedding song retains many precious mythological materials for this ethnic group with only language but no words, so that it can be passed down from generation to generation without loss, and it also highlights the values and moral standards of the Tu ancestors. In such a multi-ethnic region as the Hehuang River Basin, the myth of the Tu wedding song integrates many myth motifs of other ethnic groups, and at the same time it does not lose its own creativity and has distinct characteristics. In the process of singing the wedding song, the Tu myth can radiate new vitality, and it still has a cultural value that cannot be ignored in the contemporary society.
