What is the metaphysical concept of Confucianism?

The original book of changes: "The metaphysical refers to the Tao, and the metaphysical refers to the device", exultation. I have a vague feeling that metaphysics is more virtual and more real. Metaphysics is different from metaphysics: metaphysics refers to the category that thinking and macro belong to emptiness; Metaphysics refers to understanding things to the extreme and being rigid. Laozi has a saying that "the metaphysical refers to the Tao, and the metaphysical refers to the device", which means that metaphysical things refer to the Tao, which refers to both philosophical methods and thinking activities. Physically, it refers to concrete and tangible things or cultural relics. Generally speaking, metaphysics has two meanings. One is to look at things from an isolated, static, one-sided and superficial point of view. The second refers to the philosophy of judging things by intuition (transcendental experience). Sometimes it refers to the study of philosophical ontology. Since modern times, with the strong spread of scientific rationality in the field of humanities, traditional metaphysics has been dealt an unprecedented blow. However, from the historical process of the development of metaphysics, there are actually three forms of metaphysics: universe ontology, category ontology and meaning ontology. What scientific reason rejects is actually the universe ontology based on speculative fiction. In the post-metaphysical era, as far as meaning ontology is concerned, metaphysics has no end and will not end. It is metaphysics to talk only about form, not substance.
