It also has great uses, but more importantly, it has feng shui significance. The custom handed down from ancient times to the present, hanging a mirror on the door can resist the shaqi outside. If it is in some big families, it is definitely indispensable. But in some poor families in ancient times, people may not be able to afford a mirror, but they will also find something that can reflect light and hang it on the door, so that some monsters can be kept out and ghosts in the house can be seen, so that people can drive them out.
Of course, hanging a mirror at the entrance is also for our own convenience to tidy up our appearance and image. Be sure to wear your own clothes before going out, manage your own image, look in the mirror every day and give yourself confidence, so that you can be confident when you go out. Especially for some girls, it is very necessary to hang a mirror here, because they love beauty so much that sometimes they can't walk when they see the mirror.
So now, although there is not so much emphasis on geomantic omen, hanging a mirror at the door is something that every household will do. Don't choose a mirror that is too big, as long as it can shine on our upper body or face, because it is hung on the wall, so it can't be too heavy. If it is too heavy, it will fall down easily.
In some places, paying attention to the circle means choosing the circle, because the sky is round. In the ancient impression, the sky is beautiful and immortals live in it, so people prefer round things, and buyers can do the same. After all, there is not so much pressure now. But I think it is more advanced to put it there. According to everyone's hobbies, some people may think round mirrors look good, while others may think square mirrors look good. Everyone has different opinions and can't be forced. There are also many people who don't have mirrors in front of their doors. So don't have too much psychological burden, don't pay too much attention.
