Lam Sai-wing (traditional Chinese: 林世榮; simplified Chinese: 林世荣; pinyin: Lín Shìróng; Jyutping: Lam4 Sai3 Wing4) (1861 - 1942, or 1860 - 1943 depending on the source), was a student of the Cantonese martial artist, healer and folk hero Wong Fei-hung.
Lam was born in Nanhai district, Guangdong. He followed the customs of his ancestors and learned the traditional martial arts of his family, progressing to learning from Lin Fucheng, Wong Fei-hung and Wu Quanmei. He was eventually considered an expert in Hung Ga ("Hung family fist", a style originating from the Southern Shaolin Tiger style, known for its efficiency and widespread at the time in various secret societies), and may have also studied Fut Kuen ("Buddhist Fist", a style practiced by various Buddhist sects in Guangdong province).
He founded the Wu Ben Tang (Hall of Fundamental Study) in Guangzhou (Canton) where he taught his martial arts.
Towards the end of the Qing dynasty, Lam gained first place at a large martial arts competition that took place at the Dongjiao ground, receiving a silver medal from Sun Yat-sen as a token of recognition for his service and success.
Between 1917 and 1923, Lam served in the National Revolutionary Army of Fujian province as Chief Instructor in hand-to-hand combat.
Lam eventually moved to Hong Kong, where he started teaching martial arts. Together with his favorite students Zhu Yuzhai, Zhang Shibiao, Li Shihui, and others, he wrote three books on the three primary forms (taolu) of Hung Ga: gung ji fuk fu keun ("Taming the Tiger Fist"), fu hok seung ying keun ("Tiger Crane Paired Form Fist"), and tit sin keun ("Iron Wire Fist").
