How many ways are there to attract ghosts? How to defend yourself for advice! thank you

Want to learn Taoism! I don't know the exact name, but I know whether I can learn it depends on your date of birth, and whether there are some patterns in your horoscope, such as canopy or rare fate. You can't learn if you are all unqualified. I still advise you not to learn these things. If you really learn them, you can't throw them away in your later years ... Be careful.
