As a religious leader authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities, the "thanh đồng" in Đạo Mẫu is more of the equivalent of a priest rather than a medium or a shaman.
[2][4] When the dance is finished, the audience is allowed to approach the still-possessed medium to make offerings, petition the deity being incarnated in exchange for favours, or to have their fortune told.
[5] During early Communist rule, the practice of lên đồng (and Đạo Mẫu in general) were seen as forms of superstition and proscribed, although practitioners continued to perform rituals in secret.
In 1987, after a period of prohibition, the Vietnamese government relaxed restrictions on the practice of lên đồng, and it gradually saw a recurrence in popularity; in 2001, it was the subject of an international conference, and a foreign delegation was allowed to attend a festival at Phủ Giày in Nam Định Province.
[nb 2][6] Lên đồng is performed throughout Vietnam, and also in places with significant populations of Overseas Vietnamese, such as the United States (notably in Silicon Valley, south of San Francisco, California), Italy, France and Australia.
