窮寇
hard-pressed enemy;fleeing routed enemy
～勿追never corner a defeated enemy; do not pursue an enemy who is desperate/宜將剩勇追～，不可沽名學(xué)霸王。(毛澤東詩《人民解放軍占領(lǐng)南京》) With power and to spare we must pursue the tottering foe,And not ape Xiang Yu the conqueror seeking idle fame.(Mao Zedong’s poem Capture of Nanjing by The People’s Liberation Army)
