Qin Ming (秦明) is a character in the Chinese literary classic Water Margin. He was one of the highest ranking compatriots of Song Jiang and one of the 36 Heavenly Spirits.
Before he joined the Liangshan heroes however, he was formally a commander of the Qingzhou troops serving the Imperial Court. Nicknamed 'the Thunderbolt' (霹雳火), or 'the Thunderclap', and famed for his almost barbaric temper (which is continuously and repeatedly emphasized over the course of the novel) and thunderous voice, Qin Ming was peerless in the use of the toothed-mace and even the great Zhang Qing found him a handful. Respected for his strong sense of loyalty and bravery, it was the latter that would cost him his life when he was killed in the battle against Fang La.
