Gu Ruzhang (Chinese: 顾汝章; pinyin: Gù Rǔzhāng; Cantonese Yale: Gu Yu-jeung; 1894–1952) was a Chinese martial artist who disseminated the Bak Siu Lum (Northern Shaolin) martial arts system across southern China in the early 20th century.
Gu also learned Chaquan from Yú Zhènshēng (于振聲); Yang Taijiquan and Bajiquan from Li Jinglin (李景林); and Baguazhang, Xingyiquan from Sūn Lùtáng (孫祿堂).
Major events in Gu’s life are difficult to verify, as many of his achievements have been made legendary and may have been subject to gross exaggeration.
[1] According to legend, Gu, in the same spirit as the folk hero Huo Yuanjia, defeated foreign fighters who viewed the Chinese martial arts as an inferior system of fighting.
Gu Ruzhang's iron palm struck the horse on its back, and it fell down with a severely damaged backbone and died the next morning.
