In my dream, a master has been teaching me fortune telling.

From the perspective of time and space, there are two kinds of teachers:

One is Shi Yang, a real real-world teacher. You can find such a teacher.

One is a Yin teacher, and the other is a master of another time and space, which is called a fairy. This kind of teacher is not suitable for everyone, he can only choose you.

I have a friend who learned Taoism from an old man with white hair in his dream since he was a child. Believe it or not, the world is full of interference.
