Tao Te Ching is a philosophical poem. Zhuangzi Tian Xia Pian contains its purpose: take it as essence, take things as coarseness, take product as emptiness, and live alone in Shenfu. ..... nothing to build, the ether of the Lord, with humility as the table, and the immortality of everything in the air as the truth. Generally speaking, he took "Tao" as the origin of the universe and the highest principle of the universe, and as the ultimate, he invented self-cultivation to govern politics and others. As the saying goes, "man is everywhere, the earth follows the sky, the sky follows the Tao, and the Tao follows the nature", so human beings should learn from the earth and study the origin and essence of the Tao. The principle of Tao has two sides: nothing and two sides. Tao is often absent, nameless and intangible, and it is the beginning of all things in heaven and earth before the ghosts and gods in heaven and earth. The Tao is always there, giving birth to everything in the world and using it endlessly. The principle of Tao runs through all things, which is manifested as the fundamental law of the relative existence of all things, and the extremes of things will be reversed and eventually return. And useful, often based on nothing, "out of nothing." The sage's body has no way, and the way is naturally inaction, so as to cultivate one's morality, be quiet without desire, be careless and empty, be unconscious, be conceited and not stick to it, succeed without being born, be kind and thrifty, practice and go to China, so as to rule the world, and achieve "teaching without doing anything, without words", return the sword, leave the war, not Shang Xian and not expensive. "Those who oppose the Tao are used by the weak", and those who know the truth are conservative and humble, frustrated and resolved, mutually assured destruction, and the weak prevail over the strong. Taoist views on knowing and doing, politics and ethics are generally divorced from the old system. If the Confucian classics say "to be empty, to be quiet, to believe", "to be spiritual, to be gentle" and "to be metaphysical", that is the foundation of various Taoist practices, such as gathering the mind, forgetting to sit, being convinced, and inner alchemy. Taoism is cited as the origin of immortal life theory, such as "immortality" and "death without death" in the theory of "returning to the original" and "resurrection". Inner alchemy has played a philosophical foundation for the inner alchemy to be refined into truth and integrated with Taoism. Laojunyan in Qingyuan Mountain, Quanzhou
