In the areas in Myanmar where the Southern Buddhism is worshipped，there used to be a popular traditional custom that the young boys and girls were sent to the temple to be monks and nuns to learn early religion and culture of Buddhism． Ｒecent years，there are reports on the tonsuring of acolyte in Myanmar． The paper discusses two kinds of rituals，one of which is the Dai people's upgrading acolyte ritual in Jing?dong，Myanmar，and the other of which is the cruise ritual for sending the children to temple to be acolyte in the urban area in Bagan，Myanmar． There are four types of folk ritual bands concerned: the Dai's mini folk orchestra，the elephant － foot drum band in Jingdong area，the Burma Duoba band and mini blow and beat band in Bagan area． The paper，from the aspects of ritual customs，constitution of the band，musical fea?tures and others，studied the history of development and current situation of these folk bands，as compared with the ancient and contemporary dance and music in Yunnan － south east of Asia areas．
