1, the cockroach can be placed so that its head can pass through the door or the mine mouth. When facing the door, you can't face the door directly. You can turn your brave face a little sideways.

Don't put it in front of the mirror. Don't put your head against the toilet.
Don't let the brave dog be higher than himself, let alone put it directly on the ground.
4. Put a glass of water in front of you. Being a god beast is not a Buddha, nor is it offered by incense.
I hope my answer can help you.
