Leung Kwan (Chinese: 梁坤; pinyin: Liáng Kūn; 1815–1887), popularly nicknamed "Iron Bridge Three" or "Tit Kiu Sam", was known as 'the great master of the Hong Fist' and was one of the Ten Tigers of Canton, a group of ten of the top Chinese martial arts masters in Guangdong towards the end of the Qing Dynasty (1644–1912).
He loved studying martial techniques, and travelled around in search of friends and great masters, frequently seeking out the company of Buddhist monks.
He went on to teach martial arts at the Guangzhi dye-works at Rainbow Bridge in Canton (now known as Guangzhou) and he became an extremely well known figure.
His death was caused by over-zealous training in the "36 Point Copper Ring Pole" technique, under the monk Yuanguang at Hoi Tong Monastery.
Leung had long been an opium smoker; the monk advised him to break the habit and train in the pole technique instead.
