Historical origins

As early as the Qing Dynasty, China has had a tradition of entertaining mourners at funerals. Especially among certain ethnic minorities, such as the Tujia people, there is a tradition of “being happy at the funeral but sad at the wedding.” But the striptease was only added to the funeral entertainment menu in the 1990s. Experts partly attribute such a phenomenon to fertility worship. “In some local cultures, dancing with erotic elements can be used to convey the deceased’s wishes of being blessed with many children,” Huang Jianxing, professor of Fujian Normal University Sociology and History Department, told the Global Times. “According to the interpretation of cultural anthropology, the fete is originated from the worship of reproduction. Therefore the erotic performance at the funeral is just a cultural atavism,” media professor Kuang Haiyan interprets.
