In the vast landscape of Chinese classical literature, few scenes are as chilling as a man killing his own wife. Two such moments stand out, separated by centuries yet eerily similar: the bloody climax of the “Cui‑ping Mountain” episode in the Ming dynasty novel Water Margin (Shuihu Zhuan), and the dream‑like murder in Pu Songling’s Qing dynasty tale “Cheng Xian” (Becoming an Immortal) from Strange Tales from a Chinese Studio.
Both stories share a disturbing pattern: a “friend” pushes a husband to kill his unfaithful wife, and the husband – stripped of his former life – is forced onto a new path. In Water Margin, Yang Xiong is driven to Cui‑ping Mountain to become an outlaw. In “Becoming an Immortal”, Zhou Sheng is driven to Mount Lao to become an immortal. One road leads to banditry; the other to transcendence. Yet the mechanism of coercion is remarkably the same.
The Bloody Blueprint: Cui‑ping Mountain
The story from Water Margin is brutal and direct. Yang Xiong, a prison guard in Ji Prefecture, has a beautiful wife named Pan Qiaoyun. She commits adultery with a monk, Pei Ruhai. Yang Xiong’s sworn brother, Shi Xiu, discovers the affair. Instead of simply telling Yang Xiong, Shi Xiu kills the monk, gathers evidence, and then – crucially – manipulates Yang Xiong into killing his wife himself.
Shi Xiu suggests they take Pan Qiaoyun to Cui‑ping Mountain under the pretence of burning incense. There, he forces a confession from the maid. Then he says to Yang Xiong: “Today everything has been made clear. I leave it to you, brother, to decide what to do.” But he does not leave it to Yang Xiong. He urges: “Brother, why keep her? Cut the roots once and for all.” Yang Xiong, cornered and humiliated, kills his wife and her maid, then flees with Shi Xiu to join the outlaw band at Mount Liang.
Many scholars have noted that Shi Xiu manipulated Yang Xiong step by step. Yang Xiong did not plan to kill his wife – he was pushed into it. The true tragedy is that Yang Xiong, once a respectable official with a comfortable life, is reduced to a fugitive. Shi Xiu, by contrast, gains a place among the Liangshan heroes. The “friend” saved himself by destroying his friend.
The Motive: What Drove Them?
But here the stories diverge, and the difference reveals something profound about each author’s vision.
Shi Xiu’s motives are multifaceted and hotly debated. Scholars have analyzed them from several angles:
- Superficial motive: self‑vindication. After Pan Qiaoyun falsely accused him of “improper advances” and had him expelled by Yang Xiong, Shi Xiu’s immediate goal was to clear his name and avoid being branded a lecher for the rest of his life. He had to prove his innocence or lose all standing in the world.
- Personality‑driven: inferiority complex and vindictiveness. Coming from a lowly background, Shi Xiu was hypersensitive and fiercely resentful of any perceived slight. He was quick to take offence and, once wronged, pursued revenge with ruthless determination, caring little for the consequences.
- Deep motive: survival calculation. While no explicit evidence suggests Shi Xiu premeditated to lure Yang Xiong to Liangshan, the plot’s logic objectively achieves that effect. By destroying Yang Xiong’s family and honour, Shi Xiu ensures his brother has no path back to respectability—only the outlaws’ den remains. In this reading, Shi Xiu’s actions are a desperate bid to secure his own place among the Liangshan heroes by dragging Yang Xiong down with him.
- Alternative interpretation: jealousy. Some readers argue that Shi Xiu envied Yang Xiong’s comfortable life—his official post, his beautiful wife, his wealth and status. Beneath his righteous anger may have lurked a subconscious resentment of his brother’s stability.
These conflicting interpretations reflect the richness of Shi Xiu’s character. The great Qing dynasty critic Jin Shengtan famously called Shi Xiu “extremely vicious” and said he despised him, while others see him as a loyal friend driven to extremes. What is certain is that his actions, whatever their motive, push Yang Xiong to a point of no return.
Cheng Sheng’s motive is more pure. He is not jealous of Zhou – he owes Zhou everything. His push toward murder is not driven by selfish ambition but by a twisted form of salvation. Cheng genuinely believes that the world is corrupt and that only by severing all attachments – including love for a wife – can Zhou find peace. The wife’s infidelity may even be an illusion created by Cheng to break Zhou’s attachment. In Cheng’s mind, he is saving his friend, not destroying him.
Yet the result is the same: a woman dies, and a man’s life is irrevocably changed.
The Destination: Bandits or Immortals?
The endings of the two stories reflect the different worlds of their authors.
Water Margin was written in the Ming dynasty, a time of political turbulence. Its heroes are outlaws – men who reject a corrupt society by taking up arms. Yang Xiong joins the bandits at Mount Liang, where violence is the answer to injustice.
“Cheng Xian (Becoming an Immortal)” was written in the Qing dynasty, by a man who spent his life failing the imperial examinations. Pu Songling’s answer to injustice was not rebellion but escape – into the mountains, into Taoism, into immortality. Zhou Sheng does not become a fighter; he becomes a hermit. The violence is not public but private, not political but spiritual.
Both men are forced out of their old lives – but one is forced into a life of crime, the other into a life of contemplation. One becomes a bandit; the other becomes an immortal.
The Darker Lesson
What makes both stories so unsettling is not the adultery or the murder – it is the role of the friend. In both cases, the friend acts as a kind of moral police, enforcing a brutal code of honour that leaves no room for mercy, no space for forgiveness. The wife must die, not because she is a threat, but because she has shamed the husband. And the friend, by pushing the husband to act, ensures that the husband can never go back to his old life.
Yang Xiong cannot return to his job or his home – he is a fugitive. Zhou Sheng cannot return to his wife or his family – she is dead, and he is complicit. Both men are trapped, with only one path forward: follow the friend who led them to this point.
It is a chilling portrait of friendship as a form of control – a bond that, in the name of loyalty, destroys everything it touches.
A Final Reflection
Pu Songling himself may have been aware of the parallel. Some commentators have noted that the murder in “Cheng Xian (Becoming an Immortal)” is remarkably similar to the Cui‑ping Mountain scene. But where Shi Xiu is a villain, Cheng Sheng is a saviour – or so he believes. The story asks a troubling question: Can a good intention justify a terrible act? If Cheng truly believed that killing his friend’s wife would save his friend’s soul, does that make the killing any less wrong?
The answer, perhaps, is that in a world as corrupt as the one Pu Songling depicts, even the purest friendship can become a weapon. And sometimes, the people who claim to love us most are the ones who push us off the edge – whether onto a mountain of outlaws, or into the clouds of immortality.
In Chinese literature, the theme of “forced transformation” runs deep. Yang Xiong was “forced onto Liangshan” – a phrase that became a proverb for being pushed to rebellion by an unjust system. Zhou Sheng was “forced onto Mount Lao” – pushed not by the state, but by a friend who claimed to know what was best for him. The difference between the two is the difference between the sword and the spell – but the blood on both is equally real.
