What are the forms of chaos, infinity, Tai Chi, two instruments, four images and five elements?

Chaos refers to a state in which there is everything, but nothing can be distinguished and nothing can be seen.

Infinity refers to the state of having everything but being unable to distinguish anything.

Tai Chi refers to the state of internal order.

These two tools are orderly enough to distinguish the differences between opposites. At this time, yin and yang are distinct, so it is called two instruments.

These four images are also distinguished from each other by their opposition. Because they have four basic points, they are called four images.

Due to the opposition of various forms, the five elements formed life and gram, and finally formed an independent cycle with internal stability.
