Brief: This article tells the remarkable story of Xian Gao, a humble cattle merchant who single-handedly saved the State of Zheng from invasion in 627 BCE. When he discovered the Qin army marching to attack his unprepared nation, Xian Gao impersonated an envoy and presented the Qin general, Meng Mingshi, with twelve oxen to feign that Zheng was ready for war. This ruse successfully convinced the Qin forces to abandon their attack and plunder Hua State instead. Although the Qin army was later destroyed at the Battle of Xiao, Xian Gao’s quick wit and bravery demonstrated how diplomacy and courage could triumph over brute military force.
Ambition in the West
After the death of Duke Wen of Jin in 628 BCE, Duke Mu of Qin saw a golden opportunity. Long frustrated that Central States viewed Qin as a “western barbarian” (much like they labeled Chu a “southern savage”), he was determined to march eastward and claim hegemony.
His young generals – Meng Mingshi, Xi Qishu, and Bai Yibing – shared this ambition. Encouraged by a secret report from Qi Zi, a Qin officer stationed in Zheng, who claimed:
“Duke Wen of Jin is dead but not yet buried; Zheng’s new ruler, Duke Lan, ignores Qin and bows only to Jin. Strike now – Zheng is unprepared, and Jin won’t fight over a corpse!”
Duke Mu was convinced.
The counsel of the elders
Veteran ministers Jian Shu and Baili Xi strongly opposed the campaign:
“To attack a state during mourning is unjust. Zheng is over a thousand li away – secrecy is impossible. Even if we win, we cannot hold it. If we lose, the cost will be ruinous.”
But Duke Mu retorted bitterly:
“We’ve always played second fiddle to Jin state – like a lame donkey chasing a horse! Now that Chong’er (Duke Wen of Jin) is gone, must we stay silent in the west forever?”
Ignoring their warnings, he appointed Meng Mingshi as commander and dispatched 300 chariots toward Zheng.
A father’s tears
On departure day, Jian Shu and Baili Xi wept at the eastern gate:
“We see you leave – but we shall never see you return!”
Xi Qishu and Bai Yibing, Jian Shu’s sons, offered to stay. But their father insisted:
“You must fulfill your duty – even unto death.”
He added gravely:
“Beware the Xiao Mountains (in modern Luoning, Henan). If disaster strikes, I’ll go there to gather your bones.”
Meng Mingshi dismissed this as excessive fear. How could such doom await a bold expedition?
The merchant who became an envoy
In early spring of 627 BCE, the Qin army reached Hua state (near Yanshi, Henan). Suddenly, a man blocked their path:
“I am Xian Gao, envoy of Zheng. My lord sends twelve fat oxen to honor your arrival.”
Meng Mingshi was stunned – how did Zheng know? Trying to conceal his intent, he lied:
“We’re not going to Zheng – we’re attacking Hua State!”
Xian Gao accepted the answer, delivered the cattle, and departed.
Unbeknownst to Meng Mingshi, Xian Gao was no envoy – he was a cattle merchant. On his way to Luoyang, he’d met a fellow townsman returning from Qin who revealed the invasion plan. Realizing Zheng was defenseless during its period of mourning, Xian Gao acted instantly:
- He sent messengers racing home with the warning,
- Then drove his herd north to impersonate an official delegation.
His ruse worked perfectly.
The pivot to Hua – and the missed target
Convinced Zheng was now fortified, Meng Mingshi abandoned the original plan:
“They’re ready. A siege would drain us. Better to strike unprepared Hua State instead – plunder its wealth, and return with something to show our lord.”
So the Qin army sacked Hua – a hollow victory.
Meanwhile, in Zheng, Duke Lan received Xian Gao’s warning and investigated Qi Zi and his co-conspirators.
Qi Zi was a high-ranking official of Qin, dispatched by Duke Mu of Qin to station in Zheng together with Feng Sun and Yang Sun, assisting Zheng in defending the northern gate of its capital. In the event of war between the two states, this position enabled them to serve as Qin’s inside agents for a surprise attack on Zheng.
Finding them packing weapons and baggage, he sent a minister to say coolly:
“Meng Mingshi’s army has reached Hua state. Why aren’t you joining them?”
Exposed, the Qin agents fled under cover of night.
The seeds of disaster
Though Zheng was saved, Qin’s recklessness bore bitter fruit. On their return march through the Xiao Mountain, the exhausted Qin army was ambushed by Jin forces lying in wait. Trapped in the narrow mountain gorge, the entire Qin force was annihilated – fulfilling Jian Shu’s prophecy.
Duke Mu of Qin, devastated, publicly accepted blame and vowed reform. Yet the lesson was clear: arrogance, distance, and moral miscalculation had undone his dream.
And history remembered not the generals, but the humble merchant whose quick thinking and patriotic courage – armed only with oxen and wit – saved a nation without drawing a sword.
