Hang a picture on the bed.

You can't hang it in the east ~ purple gas comes from the east ~ hanging it in the east will block the wind and water ~ Don't draw too hard, it's best to be opposite, especially the contrast between cold and warm colors should not be too strong! You can't hang it on your head ~ it's easy to be pinned down ~ the color of the painting can't be too strong, it can be warm in summer and winter … the things in the painting can't conflict with the house, it depends on the specific situation, or I'll show you.
