Yam Kim-fai (Chinese: 任劍輝, 4 February 1913 (Lunar 29 December 1912 – 29 November 1989), also known as Ren Jianhui was a renowned Cantonese opera actress in China and Hong Kong. Yam was most notable for her unique ability to sing in the lower register. That her opera voice was indistinguishable from a male one allowed her to play either male or female roles, though she usually performed male ones. In 1989, she died at home in Hong Kong due to pleural effusion. There was no JTWROS. Yam had a will drawn up and left her estate to families, including Yam Bing Yee.
