Jenny Tseng mostly known in speaking regions as Yan Nei, is a Macau-born singer, based in Hong Kong for much of her career. Her repertoire includes both Cantopop and occasionally Mandarin songs. Among her most popular recordings were several duets with Roman Tam, such as the music from TVB's 1982 adaptation ''The Legend of the Condor Heroes''. She is the widow of kung fu movie star Alexander Fu Sheng, who died in a 1983 car accident. She and her late husband had no children; however in 1988, Tseng gave birth to a daughter, Melody. Somewhat controversially, she has refused to name the father to the present day.
In addition to singing, Tseng also acted in several films during the 1970s and 1980s. She now lives in San Francisco.
