Sun Li (孙立) is a fictional character in the epic Chinese tale Water Margin. In the novel Iron Arm, Golden Sabre, he is portrayed as being a younger martial arts brother of Zhou Tong, the military arts tutor of Song Dynasty General Yue Fei. They (and Luan Tingyu) learn martial arts from a Shaolin master named Tan Zhengfan.
Sun Li's ancestors were from Liangzhou, but he served as a garrison major in Dengzhou. Sun stood at above 8 feet, a wide bearded face and jet-black eyes. He was an excellent archer, and used a wide variety of weapons including steel rods, just like Huyuan Zhuo's. He was an impatient man and was often compared with Yuchi Gong. However, due to his paler complexion, he was nicknamed 'Sick Yuchi' (病尉迟) as people in those days think that people with pale complexions are ill.
