There is a geomantic mirror with scissors and abacus on it and a mirror in the middle. What does it mean to draw something red on the mirror?

Hang a larger convex mirror in your house, face his house, and hang it higher than his house. Then put three triangular glasses, the sharper one, and point the glass at his house and break his bagua mirror. Put two pots of ivy in your house. There is a string of five emperors' money hanging on both sides of the door, with a wax gourd below and a copper gourd in the middle. These are all inside the door, not outside. To be on the safe side, stick a piece of red paper on your gossip mirror (just two or three centimeters above it) and write God bless the people on it with a brush. The red paper is five centimeters wide and thirty centimeters long. You can also put a keeper on your door. It is sold online, and you can buy it for two or three dollars. If there is any noise in his house, please leave me a message again. When I opened the store, the store next door was not ready, and I didn't hire less people. There is too much rubbish in his house. Where's the monk? You can use crooked ways. Kill him too.
