Spirit money, in the form of golden paper ingots, made by three young Hmongs for the Hmong new year in Ban Poei, Nan province, northern Thailand.

Many Hmong people, both in Asia and the West, perpetuate traditional spiritual practices that include animism and ancestor worship.According to these beliefs, spirits inhabit animals and other natural objects, but also domestic features, such as doorways. The spirits of deceased ancestors are also thought to influence welfare and health of the living. Individuals perform rituals and supply offerings, including food and spirit money, to appease the spirits and earn their favor.
