Fortune _ telling what to learn?

You can measure anything:

Great Liu Ren, Daoism, Taiyi, Meihua Yijiu, and Liu Yi Divination. Personally, I think plum blossom is the most flexible and convenient.

There are also big swallow numbers and money divination (not very familiar)

Predict people's general fate by birth time;

Wei Zi is a fortune teller.

Physiognomy, predicting each other's nature and destiny by looking at the surface;

Palm and face.

Observation and Improvement of Environmental Atmosphere: Yin and Yang Family Feng Shui

Western divination: Tarot divination. (This is very famous in the West) Although it is not from Zhouyi, the truth is somewhat similar.

I suggest learning plum blossom easy counting and six-hexagram divination, which is more convenient and practical.
