Is there a fortune teller in Zhouyi?

Zhouyi is not a fortune teller, but it is the source of various fortune tellers in China. This matter is too profound. In 500 years, there may not be a person who is proficient in fortune telling. Birthdays are the most classic. Liuyi, Meihua Yijing (characterized by accurate measurement of specific things) and Wei Zi Doushu (extremely difficult to master and almost lost) are all branches of Yijing.
