Tangnan is a town in Fengshun County, Meizhou City, Guangdong Province, China. It is not located in Anhui; the source material identifies it as a settlement in Guangdong, in the country's south-eastern coastal region.
Fengshun County, to which Tangnan belongs, forms part of Meizhou City, a prefecture-level municipality in eastern Guangdong. The area lies inland from the coast, in a part of the province characterised by hilly terrain and a predominantly Hakka cultural background.
Beyond its administrative position within Fengshun County and Meizhou City, little verifiable detail about Tangnan is available. It is a town rather than a major city, and it should not be confused with other places bearing a similar name.
