Mirrors have an inseparable relationship with our lives. They can allow us to reflect our appearance, allow us to organize our appearance, and allow us to have a decent and tidy appearance in our daily life. In terms of living environment, there are more or more rooms with mirrors. Mirrors can make our room look bigger and make our room look more neat and tidy. Therefore, a large mirror is often installed on the wall of the entrance hallway in the narrow entrance hall to make the room look wider, and it can also supplement the lack of corners in the room with missing corners. But it should be noted that the wind and water we are talking about are actually good energy concentrated in the room. If you install a mirror at the entrance, it is best not to reflect poorly on things such as toilets or kitchen stoves. It is easy to damage your health and deteriorate your mood. Furthermore, you should not reflect on things outside the house, such as sharp angle shots, etc., which will easily hurt your family members. Also, do not reflect on the cabinets or statues, and do not reflect the darkness in the house. corners, which are prone to hallucinations and weird things. As for the subsidized corners, there are also requirements like flying stars, which will be continued in the next chapter.
