Leung Jan
Leung Jan (梁贊, aka Leung Tsan; Mandarin Chinese: Liang Zan) (1826—1901) was a Wing Chun practitioner. Leung Jan was a Chinese herbal doctor in Foshan. His name became well-known due to his wins in competitive bouts. He was called Mr. Jan from Foshan (佛山贊先生).
Leung Jan, originally named Leung Dak Wing (Liang Derong), was born between 1816–1826 (End of the Chia Ching (Jia Qing) period of the Ching (Qing) Dynasty 1796–1820), though accounts vary on the exact date. Leung Jan’s father was a herbal doctor and ran a pharmacy on Fai Jee Street. Leung Jan was the youngest of two sons born to Dr. Leung. The eldest son, Leung Dak Nam, became a businessman, while the younger Leung Dak Wing followed in his father's footsteps with his love of medical knowledge. Leung Dak Wing took over the family pharmacy (known as either Jan Sang Tong, Wing Sang Tong, Hang Lam Tong, Yan Sang Tong or Hang Chai Tong from different accounts) on Fai Jee Street in the mid-1850s, after his father died. Because of his occupation (in some accounts because of the name of his pharmacy) he came to be called Jan Sin-Sang (Zan Xiansheng, Mr. Jan) or more simply rendered, Jan Sang (Zan Sheng) by the locals.
