Xu Ning (徐宁), nicknamed the 'Metal Lancer' (金枪手), was yet another former imperial military drill instructor who joined the Liangshan heroes in the Water Margin. He stood at about 6 feet, had a fair face, a thin dark beard, and a wide waist. In fact, Xu's recruitment was the beginning of many exciting tales of mass recruitment found in the middle of the epic tale (e.g. Guan Sheng, Dong Ping, Zhang Qing), a catalyst of sorts if you will.
