Have a headache and ask someone to tell your fortune.

Is it really useful to go to a fortune teller when you are sick?

It depends on what you say! I think some intractable diseases can't be seen well in the hospital, or some serious diseases are still being treated in the hospital. Waiting for the result, you can burn incense, calculate divination and get some comfort. But don't take this thing as the only way to cure the disease, otherwise it will spoil the broth.
