The metaplasia of human beings and all things is not only derived from Yin and Yang, but also based on the five elements, that is, it recognizes the fluidity, diversity and complexity of all things in the universe. Figuratively speaking, this layer should still be a complete circle, and the five elements and four seasons are unified in heaven. The manuscript is either square or hexagonal, and there is no wrapped circle, which is because of the wrong expression.
It is put forward that everything in the universe is based on five behaviors, and the five-element system is integrated into the two-instrument system in the Book of Changes, forming the so-called "essence of the 25 th Five-Year Plan". "Line" is "Tao" and the five elements are the five stages of the operation of "Heaven". Gold travels westward, wood travels eastward, and fire travels westward.
Water is a trip to the north, while fire water in Jin Mu is southeast and northwest, that is, spring, summer, autumn and winter. So fire, water, wood and gold complement each other; Spring, summer, autumn and winter. Heaven changes at four times, and the five elements have their own characteristics.
