Vietnamese folklore cultural practices have always been closely associated with the local communities, the backbone of the nation. Yet, for thousands of years during the feudal period, folklore culture was compared unfavorably with scholarly culture and thus considered as inferior, even prohibited. In the second half of the twentieth century, some folklore cultural practices were labeled as backward and harmful superstitions vis-à-vis the ruling regime’s prescribed revolutionary culture. However, with the rise of heritage designation across the world trending toward the end of the twentieth century, many Vietnamese folklore cultural practices underwent a “thay bậc đổi ngôi” [turnaround in status and position] when identified by the state as intangible cultural heritage. This chapter provides an ethnographic account of the thay bậc đổi ngôi of Hầu đồng, the spiritual possession ritual in Mother Goddesses worship, a popular Vietnamese folk belief system.
