Meaning of the Idiom
bei shui che xin（trying to put out a blazing cartload of faggots with a cup of water）
Mencius was a famous thinker in the Warring States Period. He recommended the political idea of governing the country by benevolence to the vassal states, but no one adopted it. His students asked him the same question.
It is no doubt that benevolence can overcome inhumanity, just as water can extinguish fire. But now some advocates of benevolence seem to use a small glass of water to save the flame of a wagon full of firewood. If any one thus thinks that water cannot extinguish fire, he is in the same class as a tyrannical person, and will lose what little benevolence he has had.
[bēi shuǐ chē xīn]，原义是用一杯水去扑灭一车燃烧的柴草；比喻力量太小，无济于事。
