Go out to tell fortune and set up a stall.

If you want to tell your fortune, can a roadside stall? Is there a trusted teacher there?

Don't tell fortune, it's all fake. You think: if he can do the math, why not do it himself? Do you still have to set up a stall on the roadside to make a living? There are no masters in the world, they are all tricks of self-deception, relying on "childcare" to help him deceive people. No one believes that those so-called "wizards" have no market.
