"Bei Shui Yu Xin" is a variant of "Bei Shui Che Xin," where "Yu" refers to a cart, meaning using a cup of water to put out a cartload of burning firewood. This idiom originates from "Mencius, Gaozi I," with the original text reading "just like using a cup of water to save a cartload of firewood from burning," symbolizing insufficient strength to resolve a huge difficulty or crisis. Its deeper meaning emphasizes a severe mismatch between the method or strength and the scale of the problem, resulting in futile effort. It is mostly used to describe resources, abilities, or measures that are far from sufficient to cope with a severe situation, often carrying a tone of helplessness, irony, or warning. Culturally, it reflects the Confucian clear-eyed recognition of real predicaments, reminding people to act within their capacity or seek more effective approaches. Emotionally, it leans negative, implying a sigh over ineffective efforts.

2. Using such a simple method to tackle environmental pollution is no different from a cup of water on a burning cart of firewood—it requires a more systematic solution. (Describes measures that are mismatched with the scale of the problem and thus futile.)
