通过对婚姻桥梁的媒神“月老”形象的考索,亦可窥见汉藏文化同源而异体,故此在文学形象的层面上也有诸多同质异构的内容。婚俗是汉藏民族文化的典型呈现之一,而“月老”在两个民族中也体现出了既有文化渊源又有丰富内涵的民俗特征,体现出汉藏民族千百年来的密切交往和民俗融合的典型形象。 Through examining the images of the God of God and “Moon” in the bridge of marriage, we can also get a glimpse of the homogeneity and heterogeneity of the Han and Tibetan cultures. Therefore, there are also many heterogeneous contents at the literary level. Marriage customs are one of the typical manifestations of ethnic cultures in both Han and Tibetan areas, and “Moon-old” also shows the folk features of both ethnic origins and rich connotations in both ethnic groups. Closely linked with the typical image of folk fusion.
