Sun Tzu wrote: "The people of Wu and the people of Yue hated each other. But when they were in the same boat crossing a river and a storm hit, they helped each other like left hand and right hand."
The phrase "风雨同舟" (in the same boat through wind and rain) became the Chinese idiom for solidarity in adversity — the recognition that shared danger creates bonds stronger than prior enmity.
夫吴人与越人相恶也，当其同舟而济，遇风，其相救也，如左右手。
夫吴人与越人相恶也，当其同舟而济，遇风，其相救也，如左右手。

Core Wisdom
The storm does not care about your grudges. When the boat is sinking, the enemy becomes a partner — or you both drown.
Sun Tzu's observation is strategic, not sentimental. He is not celebrating friendship — he is noting that survival overrides prejudice. The Wu-Yue enmity was one of the bitterest in Chinese history, yet even that dissolved when both sides faced a common threat.
This principle applies to any situation where rivals must cooperate: business competitors facing market collapse, political opponents facing national crisis, estranged family members facing illness.
