The Miao people are an ethnic group distributed throughout the Guizhou, Hunan, and Yunnan provinces in China. Living in Southeast Guizhou Miao and Dong Autonomous Prefecture in Guizhou Province, the Miao in Shidong town are famous largely for their magnificent silver accessories and embroidered costumes in the traditional annual festivals, the “Sisters’ ceremony” and the Dragon Boat festival. As a subgroup of the Miao minority, the Miao in Shidong town call themselves “Dam Pu.” From August 25 until September 6, 2017, based on fieldwork and interviews in Shidong town, Southeast Guizhou Miao and Dong Autonomous Prefecture, Guizhou Province, the use of dyed materials (using a blue dye, locally called shiny cloth in Chinese) and embroidery was surveyed, in addition to the relationships between them in costume market. Findings from studies of Miao in the cities show that they persistently costume themselves in handmade clothing instead of ready-to-wear clothing, in contrast to the modern transformation of minorities in the general population. While preserving their traditions, how have the Miao people in this region changed during the modernization of China? The region is now government-controlled and tourism plans have been put in place. Considering their tourism role as a sightseeing spectacle, how to accept and deal with changes in the Miao ethnic group during the process of using their national costumes as a tourism resource, and while centering them in the tourism process must be analyzed.
