李代桃僵 Li Dai Tao Jiang
Explanation
李代桃僵，指一个人为了保护另一个人的利益，而牺牲自己，或者说承担了别人应该承担的责任。这个成语出自古乐府诗《鸡鸣》，原文是“桃生露井上，李树生桃旁。虫来啮桃根，李树代桃僵。树木深相待，兄弟还相忘。”意思是说，桃树生长在露水滋润的地方，李树生长在桃树旁边。虫子来咬桃树的根，李树就代替桃树而死。树木之间尚且互相帮助，兄弟之间反而会互相遗忘。后来这个成语就用来比喻兄弟互相爱护互相帮助，后来也用来比喻互相顶替或代人受过。
Li Dai Tao Jiang means one sacrifices oneself to protect the interests of another, or takes responsibility for what others should have. This idiom is from the ancient Chinese poem "Ji Ming" (鸡鸣) in "Gu Le Fu" (古乐府). The original text is: "Tao sheng lu ying shang, Li shu sheng tao pang. Chong lai nie tao gen, Li shu dai tao jiang. Shu mu shen xiang dai, xiong di hai xiang wang." It means that a peach tree grows in a place covered with dew, and a plum tree grows beside the peach tree. When an insect bites the roots of the peach tree, the plum tree dies for the peach tree. Trees help each other, but brothers forget each other. Later, the idiom was used to describe that brothers love and support each other. Later, it was also used to describe that they replace each other or take responsibility for others.
