Standoff Between Two Armies:
The Young King Before 400,000 Troops
In the spring of 213 AD, dark clouds of war hung over the river at Ruxukou, Anhui. The 58-year-old Cao Cao personally led 400,000 troops south, only to be firmly held back north of the Yangtze River by 31-year-old Sun Quan with just 70,000 soldiers.
The Wu warships formed a tight formation, and the soldiers wore bright, gleaming armor. The young Sun Quan even sailed a light boat directly into Cao Cao's naval camp, beating drums and playing music five or six li from the enemy lines, patrolling with complete composure.
Standing on his tower ship, Cao Cao gazed at his heroic opponent across the river and sighed deeply, uttering a famous line that would echo through history:
"If I were to have a son, he should be like Sun Zhongmou. The sons of Liu Jingsheng are nothing but pigs and dogs!"
(Tun: piglet; Quan: dog. Cao Cao insulted Liu Cong, son of Liu Biao, for his cowardice, using him to highlight Sun Quan's heroic spirit.)
Eight Words to Repel the Enemy: Sun Quan's "Threat Letter" and Cao Cao's Great Wisdom
The two armies faced each other for more than a month, and the river level began to rise. One day, Cao Cao received a letter personally written by Sun Quan, containing only 12 characters:
"The spring river is rising; Your Excellency should leave at once."
On the back of the letter was a short line:
"As long as you live, I shall never know peace."
Faced with such a blunt "threat," Cao Cao smiled and said to his men: "Sun Quan is not deceiving me." He immediately ordered a retreat.
When his generals expressed confusion, Cao Cao explained: "Jiangdong is protected by natural fortifications, and Sun Quan has great courage. A fierce attack will only lead to defeat."
This seemingly "humiliating" retreat was in fact the strategic self-discipline of a Three Kingdoms overlord: "It is no shame to retreat when victory is unattainable."
A Warlord's Eye for Talent: Leadership Philosophy Read Between Insults
Why did Cao Cao hold Sun Quan in such high regard?
He insulted Liu Cong out of anger at his incompetence: Liu Cong, son of Liu Biao, controlled a powerful army in Jingzhou yet surrendered without a fight, ruining his father's legacy. He praised Sun Quan out of respect for his ability to uphold his family's cause: Sun Quan took control of Jiangdong at 18, quelled internal rebellions, repelled powerful enemies abroad, and greatly expanded his father and brother's foundation.
The philosopher Xiong Shili commented: "Lord Cao's greatness lay in his ability to see through cunning, and his cunning lay in his ability to preserve himself."
In this standoff, Cao Cao saw not only his opponent's strength, but also the most precious quality of a leader: "Daring to confront, yet skilled at reconciling."
Historical Lesson: The Truly Strong Never Fear Acknowledging Their Rivals
Looking back at the Battle of Ruxukou after a thousand years, Cao Cao's retreat was by no means cowardice.
He understood: "Peace gained through struggle endures" — by acknowledging Sun Quan's strength, he avoided mutual destruction.
He also understood: "Life and work are a constant struggle" — rather than fighting to the death on unfavorable terrain, it was wiser to preserve strength and wait for the right moment.
As Sun Quan wrote in his letter, "As long as you live, I shall never know peace." True heroes understand best how to respect their opponents.
