What figures or classics of China embody metaphysics?

There is a saying in the Book of Changes that "the metaphysical person refers to the Tao, while the metaphysical person refers to the device". The concept of Tao in Laozi's Tao Te Ching is: "Things are born in harmony. Lonely and lonely, independent without change, walking around without danger, but the mother of heaven and earth doesn't know its name, and the strong word is "Tao"

The philosophical concept of western metaphysics refers to the origin of the world and the first thing in the universe. Because the western explanation of this concept has not been well explained, there are religious gods about the origin of the world, such as Catholicism and Islam. And become the mainstream thought.

Because the ideas about the origin of the world in Tao Te Ching and the Book of Changes are more essential and perfect than those in the west, it is impossible for religious idols about the origin of the universe to appear in the history of China.
