Introduction to metaphysics

Metaphysics, the word "Xuan" here, comes from a sentence in Laozi, "Xuan is both mysterious and mysterious, and it is the door to all miracles." Metaphysics was originally a philosophical term, referring to a philosophical trend of thought with Laozi as the research core in Wei and Jin Dynasties. In modern times, it refers to all theories that study unknowable ontology. In the debate between science and metaphysics, its connotation has been extended to the extreme, and everything in science that is unknowable, incredible, unexplained and untouchable seems to have been swept into the category of metaphysics. Metaphysics, also known as Neo-Taoism, is the study and explanation of Laozi, Zhuangzi and Zhouyi, which originated in Wei and Jin Dynasties. Metaphysics is a trend of thought advocating Lao Zi and Zhuang Zi in China from Wei Jin to the middle of Song Dynasty. It can also be said that Taoism is a new way of expression, so it is also called new Taoism. Its ideological trend lasted from the end of Han Dynasty to the middle of Song Dynasty. Metaphysics was the mainstream thought that replaced Confucian classics in Wei and Jin Dynasties. Metaphysics is "profound learning", which is based on "ancestors narrate Lao Zi and Zhuang Zi", and Lao Zi, Zhuangzi and Zhouyi are called "San Xuan". Taoist metaphysics is also the only knowledge besides Confucianism that has been designated as an official school.
