Thiên Hậu is the Vietnamese transcription of the Chinese name Tianhou (“Empress of Heaven”), an epithet of the Chinese Goddess of Sea, Mazu, the deified form of Lin Moniang, a medieval Fujianese girl credited with saving one or some of her family members from harm during a typhoon through her spiritual power. Although officially unrecognized by both the governments of Mainland China and Taiwan, the faith is popular in the maritime southern provinces of China and, especially, on Taiwan and among the Chinese diaspora. In Vietnam, she is also sometimes known as the “Lady of the Sea” (Tuc Goi La Ba).
