The word "good as water" comes from the eighth chapter of Laozi's Tao Te Ching:
"Good if water. Shui Hudequan's calligraphy. It is a few things to be good for all things and evil for all. Living in a good place, kind-hearted, kind-hearted, good at words, good at politics, good at doing things, good at dealing with people. Husband is not noisy, and there is nothing special. "
Goodness: supreme. Water: lifeless, clear and transparent, uncontroversial with everything; But it can naturally flow from high to low, or it can quietly and naturally gather in one place. Kindness is like water: kindness is like water, kindness is natural, and kindness is unintentional. That's great.
