Bruce lee's real name

Lee's Cantonese given name was Jun-fan. The name literally means "return again"; it was given to Lee by his mother, who felt he would return to the United States once he came to of age.] Because of his mother's superstitious nature, she originally named him Sai-fon, which is a girl's name. The English name "Bruce" was thought to be given by the hospital attending physician, Dr. Mary Glover. 

Lee had three other Chinese names: Li Yuanxin (李源鑫), a family/clan name; Li Yuanjian (李元鑒), as a student name while he was attending La Salle College, and his Chinese stage name Li Xiaolong (李小龍; Xiaolong means "young dragon"). Lee's given name Jun-fan was originally written in Chinese as 震藩, however, the Jun (震) Chinese character was identical to part of his grandfather's name, Lee Jun-biu (李震彪). Hence, the Chinese character for Jun in Lee's name was changed to the homonym 振 instead, to avoid naming taboo in Chinese tradition.
