Ancient fortune tellers all claimed to be teachers.

A fortune teller is a person who is good at using divination, astrology and other techniques to predict the future and explain fate for people. Fortune tellers, also known as fortune tellers or numerologists, are those who are good at using divination, astrology, astrology and other technologies to predict people's future and interpret their destiny. People often get advice and guidance based on their faces, palms and dates of birth. However, with the progress of modern science and the prevalence of rational thinking, the professional status of fortune tellers is gradually marginalized, and most people regard it as a superstitious and useless industry. Ancient fortune-telling has a long history, which began in the Shang and Zhou Dynasties. With the change of dynasties and historical changes, the duties of fortune tellers have gradually developed into a specialized profession. Since the Western Zhou Dynasty, astronomy, geography, mythology, divination and other methods have been applied to the practice of fortune tellers. In the Western Zhou Dynasty, tortoise shells and ox bones were the main divination schools, while in the late Eastern Zhou Dynasty, Liu Ren, Bagua and other divination schools were mainly the Book of Changes. Despite the change of dynasties and historical changes, fortune tellers still have an extremely important position in the future inheritance and development process. In the Tang Dynasty, Kang Youwei said, "Stealing chickens and not eating rice, splitting white stocks and worshiping the mysterious yellow".
