The Fateful Decision to Invade Jin
In 382 CE, Fu Jian, Heavenly King of Former Qin, stunned his court by declaring his intent to launch a full-scale invasion of the Eastern Jin dynasty.
“For over twenty years I’ve pacified the four directions – only the southeast remains. I cannot eat or sleep thinking of it! With 970,000 troops, I shall lead this campaign myself. What say you?”
Minister Zhu Tong immediately flattered him: “The Jin ruler will surrender before battle even begins! Your unification of All-Under-Heaven will surpass all ancient sages!” Fu Jian beamed:”This is my lifelong dream!”
But the rest of the court fell silent – then erupted in opposition.
Quan Yi warned: “Jin is weak, yet seen as the legitimate dynasty. The Xie and Huan clans still produce capable men. Victory is not assured.”
Shi Yue added:”The Yangtze is a natural barrier. As Confucius said, ‘If distant peoples are not submissive, one should cultivate cultural virtue and moral influence to attract them.‘ Strengthen our realm and wait.”
Furious, Fu Jian retorted: “I fear no river! When Jin conquered Wu, didn’t they cross the Yangtze? With my armies, we could ‘cast whips into the river and stop its flow’ tóu biān duàn liú)!”
Still, dissent raged. Dismissing the assembly, he summoned only his trusted younger brother, Fu Rong – a brilliant general and judge.
“Great affairs are decided by one or two minds,” Fu Jian insisted. “Let us decide together.”
To his shock, Fu Rong pleaded:”Do not go to war. The south holds heaven’s favor; Jin has committed no grave fault; our soldiers are weary. And – most dangerously – the Xianbei, Qiang, and Jie within our ranks may rebel once our army departs.”
Tears streaming, he invoked Wang Meng’s deathbed warning: “You called him your Zhuge Liang – how can you ignore his last words?”
Fu Jian turned away, face flushed with anger.
Even his favorite consort, Lady Zhang, begged him:”Sages follow the Way of Heaven. If all counsel against war, why persist?”
He snapped:”War is no woman’s concern – be gone!”
Monks, ministers, even the famed Buddhist master Dao’an came to plead. All were ignored.
In autumn 383, Fu Jian marched south with hundreds of thousands – Fu Rong leading the vanguard, a fleet sailing from Shu down the Yangtze. The mightiest army in decades surged toward destiny.
The Trap at Fei River
The Jin, though outnumbered, were ready. Under the calm leadership of Xie An, they appointed Xie Shi as Grand Commander and Xie Xuan as vanguard. They evacuated civilians north of the Huai River, stripped the land of supplies, and drilled elite troops – including the famed Beifu Army.
Fu Jian sent Zhu Xu, a former Jin general who had “defected,” to demand surrender. But Zhu Xu was a double agent. Meeting Xie Shi, he revealed:
“I am still loyal to Jin! Fu Jian claims a million men – but many haven’t arrived. Strike now, while his forces are scattered!”
Xie Shi agreed. That night, Liu Laozhi led a surprise raid on the Qin vanguard, forcing them to retreat to Shouyang (modern Shou County, Anhui).
From the city walls, Fu Jian and Fu Rong surveyed the Jin camp across the Fei River. The enemy formations were orderly; behind them, the trees on Bagong Mountain swayed in the wind – so densely that they seemed like hidden troops.
“Grass and trees – all look like soldiers!” Fu Jian gasped, suddenly uneasy.
Days later, the Jin sent a message:”Withdraw your army slightly – let us cross the river for fair battle.”
Fu Jian saw a trap-turned-opportunity:”We’ll feign retreat, then crush them mid-crossing!”
But the order backfired catastrophically.
Most Qin soldiers – conscripts from Han, Xianbei, and Qiang tribes – had no loyalty to Fu Jian. At the command to retreat, panic spread. Zhu Xu, amid the ranks, shouted:”The Qin army is defeated! Flee!”
Chaos erupted. Men stampeded westward. As Jin troops began crossing, the Qin lines collapsed entirely.
Autumn winds howled; distant cranes cried. To terrified ears, every gust sounded like enemy shouts”wind and crane cries bring alarm”.
In the rout, Fu Rong’s horse fell. Before he could rise, Jin soldiers cut him down – the very man who had warned against the war, now its first noble casualty.
The End of an Empire
The Qin army disintegrated. Over half were killed or deserted. Fu Jian fled alone, wounded by an arrow, whispering in shame:
“I ignored wise counsel… How can I face the world again?”
Back in Chang’an, rebellions exploded. Former vassals – Murong Chui (Xianbei), Yao Chang (Qiang), and others – declared independence. The north, unified just years before, shattered overnight.
Seeking to draw enemies away, Fu Jian abandoned Chang’an and hid in the mountains. But Yao Chang, once his trusted general, now led a Qiang army that captured him near Xinping (Binxian, Shaanxi). Imprisoned in a temple, Fu Jian was offered mercy if he surrendered the imperial seal.
He refused:”I would rather die than hand the Mandate to a traitor.”
Yao Chang ordered him to commit suicide. Before doing so, Fu Jian turned to Lady Zhang and his daughter Fu Baojin:
“I cannot let them defile my child after my death.”
He killed his daughter, then hanged himself. Lady Zhang drew her sword and followed him in death.
At forty-seven, Fu Jian perished – a tragic figure whose vision outpaced his judgment.
Yao Chang posthumously honored him as “Martial and Resolute Heavenly King” – then founded the Later Qin, ruling with Han-style administration and swiftly consolidating power.
Fu Jian’s grandson, Fu Deng, held out in Longdong (Pingliang, Gansu) until 394, when Later Qin finally extinguished the Former Qin remnant.
The Hollow Victory of Jin
Though victorious, Eastern Jin gained no lasting peace.
Xie An, Xie Shi, and Xie Xuan – architects of Fei River – died soon after. Power fell to Sima Daozi and his son Sima Yuanxian, who ruled tyrannically, plundering the people and ignoring the throne.
Emperor Xiaowu (r. 372–396), who had reigned since age ten, grew into a dissolute drunkard. One night, drinking with Consort Zhang, he mocked her:
“You’re nearly thirty – time to be deposed. I want younger women!”
Insulted and enraged, she and her maids smothered him with a quilt that very night.
His son, Emperor An, succeeded him – a mentally impaired ruler reminiscent of the infamous Emperor Hui of Western Jin. Real power lay with the Sima regents.
Thus, both north and south descended into decay:
- The north fractured into warring states;
- The south rotted from within.
The dream of unity died at Fei River – not just for Fu Jian, but for an entire era.
