Don't wear it on your body for mending if your clothes are torn or buttons have fallen off. If it is too late to replace it, it must be worn on the body for mending. The person to be sewed should have a straw stick or mat in his mouth, and the seamer should read in his mouth: "If you sit and mend, you will be hurt by stealing." It is said that as long as you have a grass stick in your mouth, you will understand that others misunderstand that you are stealing, otherwise, as long as people lose something, they will suspect that you have stolen it. In fact, it is to prevent the person being mended from moving, so as not to hurt people with steel needles. If you have a straw in your mouth, focus on the straw, and of course you won't move.
