What is the name of the Taoist underworld capital?

The Taoist underworld capital is Fengdu, especially known through the religious complex called Fengdu Ghost City.

Fengdu is associated with Mount Ming in present-day Fengdu County, Chongqing, China. Taoist traditions developed the site into an administrative realm of the dead, populated by divine officials, judges, and ghost bureaucrats. Later Chinese religious culture blended Taoist, Buddhist, and local ideas, giving Fengdu its familiar image as a city of judgment and punishment after death.

Legend connects the name with two Eastern Han figures, Yin Changsheng and Wang Fangping, who were said to practice Taoism on the mountain and become immortals. Their names were later associated with Yinwang, a phrase interpreted as “King of Hell,” helping establish Fengdu’s underworld reputation.

Fengdu is often confused with Diyu, the broader Chinese underworld or hell, and with Youdu, the “Dark Capital” found in older mythological descriptions. Naraka belongs primarily to Buddhist cosmology, while Yama is a judge or ruler figure rather than the name of the Taoist capital. The modern Ghost City is a temple and pilgrimage complex modeled around these afterlife traditions.
