Real name Jiang Zhong (
蒋忠), nicknamed
门神 ('door-god') for his towering build. Chapter 29 of 《
水浒传》 —
武松醉打蒋门神 ('Wu Song, drunk, beats Jiang Menshen') — is a set-piece of Chinese martial-fiction: Wu Song deliberately drinks at every tavern on the way to Happy Grove to limber up, then demolishes Jiang with the 'jade-ring step' (
玉环步) and 'mandarin-duck leg' (
鸳鸯脚) kick-combination.
