In Romance of the Three Kingdoms Chapter 36, a pivotal transition unfolds: the departure of Xu Shu (courtesy name Yuanzhi), Liu Bei’s first true strategist, marks not just a moment of sorrow, but the prelude to a greater destiny. While steeped in dramatic fiction, this chapter bridges the gap between Liu Bei’s early struggles and the arrival of Zhuge Liang, the legendary “Crouching Dragon” who would shape the fate of Shu Han.
Though historical records offer a more pragmatic account of Xu Shu’s defection, the novel’s emotional narrative – crafted by Luo Guanzhong – elevates this episode into a mythic turning point, where loss becomes revelation, and grief gives way to hope.
Cao Ren’s defeat and Cao Cao’s scheme
The chapter opens with Cao Ren’s humiliating loss at Xinye, where Xu Shu’s tactical brilliance enables Liu Bei to repel a superior Wei force. Impressed – and alarmed – Cao Ren returns to Cao Cao and lavishly praises Xu Shu’s genius. Determined to acquire such talent, Cao Cao consults his strategist Cheng Yu, who devises a ruthless plan rooted in Xu Shu’s greatest virtue: filial piety.
Knowing Xu Shu is devoted to his mother, Cheng Yu advises:
“Bring his mother to Xuchang, then forge a letter in her hand begging him to come.”
Cao Cao follows through: Xu Shu’s mother is taken to the capital, and a fake letter – pleading illness and imminent death – is sent to Liu Bei’s camp.
A tearful farewell and a fateful recommendation
Upon receiving the letter, Xu Shu is distraught. Bound by Confucian duty, he resolves to leave immediately. Liu Bei, heartbroken at losing his most trusted adviser, weeps with him. In a now-iconic gesture of affection, Liu Bei orders trees along the road to be cut down so he can watch Xu Shu’s retreating figure for as long as possible – a symbol of his profound regret and admiration.
Deeply moved by this display, Xu Shu rides partway, then turns back. He tells Liu Bei:
“There is a man in Nanyang named Zhuge Liang, styled Kongming – a crouching dragon. If you can secure his service, your grand design will surely succeed.”
When Liu Bei asks how Zhuge Liang compares to him, Xu Shu humbly replies:
“I am but a flickering candle; he is the sun and moon.”
This moment – dramatized as “recommending Zhuge Liang on horseback” – becomes one of the most celebrated acts of selfless loyalty in Chinese literature.
Tragedy in Xuchang: The mother’s sacrifice
Meanwhile, in Xuchang, the truth unravels. When Xu Shu arrives, his mother learns he abandoned Liu Bei – the virtuous lord – for a forged plea. Overwhelmed by shame and fury, she denounces Cao Cao as a traitor to the Han and hangs herself.
Consumed by guilt and rage, Xu Shu vows:
“I shall never devise a single strategy for Cao Cao for the rest of my life.”
Though historically unsubstantiated – records indicate Xu Shu’s mother did not die by suicide – this tragic climax reinforces the novel’s moral framework: true loyalty cannot be bought, and filial duty must never compromise righteousness.
Liu Bei’s first step toward destiny
Before departing, Xu Shu also leaves Liu Bei with one final stratagem: a plan to capture Fancheng using a feigned retreat. Liu Bei executes it successfully with Zhang Fei and Zhao Yun, securing a temporary stronghold.
Yet the real victory lies ahead. With Xu Shu gone, Liu Bei sets his sights on Longzhong, preparing to visit the thatched cottage of Zhuge Liang. Thus, Xu Shu’s departure – though a grievous loss – becomes the catalyst for a greater alliance, setting the stage for the Three Visits and the rise of Shu Han.
History vs. Fiction: A note on authenticity
While Romance of the Three Kingdoms dramatizes Xu Shu’s exit as a tale of deception and maternal sacrifice, Chen Shou’s Records of the Three Kingdoms (Sanguozhi) presents a simpler truth:
- Xu Shu’s mother was captured during Cao Cao’s 208 southern campaign, not via a targeted plot.
- There was no forged letter, and no suicide.
- Xu Shu defected out of necessity, not trickery.
Nevertheless, Luo Guanzhong’s version endures because it serves a deeper purpose: to sanctify Zhuge Liang’s entrance and frame Liu Bei’s quest as divinely ordained. In this light, Xu Shu is not merely a strategist – he is the herald of destiny.
