Are there really ghosts around us?

There is a ghost, but it won't hurt you, as long as there is no hostility. Just go to the drugstore to buy some cinnabar and wrap it in red cloth. Those who don't believe in ghosts can sleep with their beds facing the door and feet facing the door. Sleep for two weeks and see how it goes. You can try if you don't believe me. Then you'll know if there is. Good luck. I hope you're not scared out of your wits.
