A neighbor’s trash can is placed directly in front of my door, which is harmful to me. How to solve the problem?

If this incident affects the mood of your whole family, then the feng shui of your home has begun to change. First of all, it is best to maintain a good relationship between neighbors, which will be good for each other's wealth. If you deliberately seriously hurt each other or affect the mood of both parties every day, it will not be a good thing for each other. Secondly, you can go to your neighbor to talk. Talk about telling you taboos and see if your neighbors are willing; in the end, it depends on your neighbors' attitude. If he accepts your suggestion, everyone is happy; if he doesn't, all you have to do is put a round mirror on your door.
