《蔡龙虎》是侗族民间戏剧的传统剧目,讲述了一对孪生兄妹在历经劫难而互不知情的情况下结为夫妇,最终认祖归宗,获赠家产,一家善终的故事。剧中“兄妹婚”母题神话虽是人类童年时代产物,但它并没有随着岁月的流逝而完全成为历史的化石,而是以原来的状态或变形的形式仍存活、沉积在现代乃至当今许多民族的与婚姻有关的众多民俗事象中。对侗族而言,兄妹为婚的习俗尽管仅见于神话,在现实中早已消失,但存在于姑表之间的亚血缘婚直到上世纪八十年依然存在。作为通过戏剧的文化表演,《蔡龙虎》曲折地重温与再现了人类婚姻历程所经历“血缘婚”的遥远现实。 “Cai Long Hu” is a traditional repertoire of Dong folk plays. It tells of a twin brother and sister who became married to each other without knowing each other. Although the motif of my brotherhood is not a product of the childhood of mankind, it has not completely become a fossil of history with the passage of time, but survives in the original state or deformation, and is deposited in modern times And many of today’s many ethnic marriage-related folk customs. For the Dongs, siblings who marry their siblings are disappearing in reality although they are only seen in the mythology. However, the kinship marriages existing between their aunts and their wives remain undoubtedly eighty years of last century. As a cultural performance through the drama, “Cai Longhu” twists and turns and reappears the far-reaching reality experienced by human marriages.
