避其锐气,击其惰归 is a Chinese idiom (chengyu) meaning “to avoid engaging an enemy or opponent when they are at their strongest and most spirited, choosing instead to attack when their morale is low or they are fatigued and retreating”. Literally, “Avoid their sharp spirit, strike when they are weary and retreating”.
In 684 BC, the State of Qi, relying on its strength, attacked the State of Lu. Duke Zhuang of Lu led his army to confront them at Changshao.
When the two armies met, the Qi army beat their war drums. However, the Lu army, under the command of Cao Gui, did not beat their drums, choosing to avoid the enemy's initial fierce momentum.
By the third beating of the Qi army's drums, their morale had already dwindled, and only then did the Lu army beat their drums for the first time. The Lu army, relying on this surge of morale, defeated the Qi army despite being outnumbered.
