In real life, are there any occupations such as Yin and Yang teachers?

Teachers of Yin and Yang originated in China, and there are still teachers of Yin and Yang in some parts of China. Can be said to be a fortune teller, can also be said to be an illusionist. Not only do they know how to look at the stars and face each other, but they can also measure directions, know disasters, draw spells and perform illusions. People also realize that invisible forces, such as fate, soul and ghost, have the ability to dominate these things. The organization formed by the gathering of Yin and Yang teachers is called "Yin and Yang Road". Japanese "Yin-Yang Daoism" originated from the theory of Yin-Yang and Five Elements in China's contention period. In the age of scientific ignorance, in order to avoid disasters, people always hope to know the changes of heaven and earth in advance, and the appearance of "Yin-Yang and Five Elements Theory" makes this wish come true. His masterpiece is the Book of Changes, which has been circulated since the Zhou Dynasty.

In other words, during the Warring States period, there was a school that advocated the theory of Yin-Yang and Five Elements, called "Yin-Yang School", whose main representatives were Zou Yan and Zou Shuang of Qi. With the complexity and diversity of the world, the simple way of thinking that everything is dichotomous can no longer explain what is happening in front of us. Thus, a new way of thinking, such as "Eight Diagrams", is derived, which is used to express the movement and changes of Yin and Yang, and to express various natural phenomena, and can be used to calculate the passage of time, natural changes and various opportunities in life. The wise ancients then arranged the explanations of these phenomena into the Book of Changes, and the reference book handed down to this day in the Zhou Dynasty is the Book of Changes. The "Five Elements Theory" is developed from Jin Mu's theory that five basic substances, fire, water and earth, are "constantly changing in cycles". By studying the theory of Yin-Yang and Five Elements, we can draw up a calendar from the calculation of celestial movement and master everything in the world. Later, astronomers, calendar experts and five-element experts specializing in celestial bodies were developed.
