Cao'an (Chinese: 草庵; pinyin: Cǎoān; Pe̍h-ōe-jī: Chháu-am; literally: "thatched nunnery") is a temple in Jinjiang, Fujian. Originally constructed by Chinese Manicheans, it was viewed by later worshipers as a Buddhist temple. This "Manichean temple in Buddhist disguise" is seen by modern experts on Manichaeism as "the only extant Manichean temple in China", or "the only Manichean building which has survived intact".
The temple is located on the southern slope of Huabiao Hill near Shedian Village just west of downtown Jinjiang. Jinjiang is part of Quanzhou, which was known historically as "Quanzhou Prefecture"; the location is some 50 kilometres (31 mi) south of downtown Quanzhou.
He Qiaoyuan (1558-1632) explained in his local history, the Book of Fujian (Chinese: 闽书; pinyin: Mǐnshū), that Huabiao Hill's name comes from the fact that it and the nearby Lingyuan Hill, look like a pair of huabiao.
The temple as it exists today is not too different from a typical Buddhist temple of its region. It is a two-story granite building with the worship space downstairs and living space for a few priests upstairs.
