A good fortune-telling book.

Which is easier, the eight-character or the strange door?

The horoscope is specially used to predict people's fate, so you can't use it in things.

Qimen's prediction range is wider. Besides predicting people's fate, it can also predict many things, such as weather, travel, finding a job and seeking money.

Taoist magic belongs to the highest foresight, and the eight characters belong to the intermediate foresight. In contrast, eight characters are more studious. If there is no foundation, you can get started in less than half a year. Learning a strange door is not a year without getting started.
