Background
Slender in figure with his arms long and skinny, Yang Chun is nicknamed "White Flower Serpent" for his appearance. He is a good fighter who uses a long sabre.

Originally from Jieliang (解良; in present-day Yuncheng, Shanxi), Yang Chun leads a band of outlaws at Mount Shaohua (少華山; southeast of present-day Hua County, Shaanxi), taking the third position after Zhu Wu and Chen Da. Whenever their grain stock runs low, the three would plunder the nearby counties for replenishment.

Befriending Shi Jin
One day Chen Da goes to raid the well-stocked Huayin County dismissing objection from Zhu Wu, who fears he would run into the formidable fighter Shi Jin of Shi Family Village. As foreseen by Zhu, Chen is captured by Shi when he tries to get through the village.

Yang Chun suggests battling it out with Shi Jin to save Chen Da. But Zhu Wu believes a psychological tactic might work. So the two go to Shi to plead to be arrested as well so as to fulfil their oath of dying together. Moved by their bond, Shi Jin frees Chen Da and befriends the three. Henceforth, the two sides often exchange gifts and visit each other for drinks.

One day a hunter finds a reply letter from Mount Shaohua on a servant of Shi Jin, who has fallen drunk in a grove after an errand to invite the outlaws to attend a feast at his master's house. The matter is reported to the authorities, which sends an arrest party to Shi's house on the night of the gathering. Finding his manor besieged, Shi Jin burns it down and fights his way out with the bandit chiefs. They get to Mount Shaohua safely, where Shi Jin becomes the chief after failing to locate his teacher Wang Jin in Weizhou.

Joining Liangshan
Shi Jin tries to save a woman abducted by Governor He of Hua Prefecture, or Huazhou, but falls into the latter's trap and is captured. Lu Zhishen, who has come to invite Shi Jin to join the Liangshan Marsh, tries to rescue him but also falls into He's ambush. The Mount Shaohua outlaws turn to Liangshan for help. At Huazhou, the forces from Liangshan lures He out of the city and kills him. After Shi and Lu are rescued, the Mount Shaohua bandits, including Yang Chun, are absorbed into Liangshan.

Campaigns and death
