Lao Zi's Tao Te Ching Chapter 8: Good as water. Water is good for all things without dispute, and evil for all, so it is a few words. 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 just indisputable, so there is nothing special. There are two explanations: 1. The heart should be as clear and calm as a deep pool, without interference from the external environment. 2. Thought should be as deep as an abyss, not shallow or grandiose. Deep and quiet, broad and transparent.
