Although the Tao Te Ching has only 5,000 words, no one can say that he fully understands its full meaning since ancient times. Because the perspective and mentality of Tao Te Ching are different, there will be different understandings. And its author, Lao Zi, was then the curator of the museum, the curator of the library and the curator of the archives. He has a wealth of knowledge and insight, which is due to the convenience of his position. At the same time, he is a thoughtful man with a great preference for water, so he likes to study water, so as to learn about life, life and even heaven and earth by analogy! Therefore, to read the Tao Te Ching, we must first understand its author, and then understand the Tao Te Ching in a way similar to its author's thinking, so as to understand it roughly!
