From Chapter 8 of Laozi's "Tao Te Ching".

The original text is as follows: "The supreme good is like water. Water is good for all things without fighting. It is what everyone hates, so it is close to the Tao. Live in a good place, have a good heart, be kind and benevolent, speak good faith, govern well, and do good things. , when moving good."

Meaning: The highest goodness is like water. Water is good at nourishing all things but does not compete with all things for benefit. It stays in a humble place that many people dislike, so it is closest to "Tao".
