滴水之恩，当涌泉相报

滴水之恩，当涌泉相报

Literally means:

the favor of a drop of water shall be returned with a gushing spring

Actually means:

a small favor shall be returned substantially

滴水, a drop of water, metaphorically refers to a small number or quantity. 涌泉, a constantly gushing spring,refers to a large number or quality.

This phrase means that the favor done to you by others should be substantially returned even if it is only a small one. Commendatory.

滴水，在这里比喻数量少。涌泉，不断往上冒的泉水，这里比喻数量多。

滴水之恩，当涌泉相报，人家给你的好处即使是一点点，也要多多地报答。具有褒义色彩。
