Origin Story
东汉末年，曹操用计打败了吕布，占领徐州。吕布败走下邳城，闭门不战，曹操施行大水淹城。吕布为了稳定军心，下令军队戒酒色，并对违反军令者绝不轻饶，最终导致部下哗变，吕布被俘，曹操立即处死了他。这个故事说明，即使是强悍的吕布，在面临内乱和外敌的情况下，也不能对违反军令的行为姑息养奸，否则后果不堪设想。
At the end of the Eastern Han Dynasty, Cao Cao used strategy to defeat Lü Bu and occupy Xuzhou. Lü Bu fled to Xiapi City, refused to fight, and Cao Cao ordered a great flood to submerge the city. To stabilize the morale of his army, Lü Bu ordered the army to abstain from alcohol and sex, and would not spare anyone who violated the military order, ultimately leading to a mutiny. Lü Bu was captured and Cao Cao immediately executed him. This story shows that even the powerful Lü Bu, in the face of internal strife and external enemies, could not condone violations of military orders, otherwise the consequences would be disastrous.
