What is the fortune-telling major?

What should I learn in fortune telling?

Learn "righteousness and virtue" first, then "righteousness". If you want to be an ordinary fortune teller, you must learn Yi, Yi is the source of Tao, you must master the basic knowledge of Yin and Yang, and you must know the calendar. These are the most basic. If you want to be a professional fortune teller, you should further deepen your self-cultivation and knowledge content, not only to learn Yi-ology, but also to study law, astronomy, geography, politics, medicine and science. Yi-ology is a social practical science, and it is also important to know our times.
