There was a big mirror on the right wall opposite my house when I entered the door, not facing the door. Is this harmful to feng shui?

There should be no problem if the mirror is not facing the door, but it will also bring out some wealth. If it is not to ward off evil spirits, it is recommended not to use mirrors. Also, your shoe cabinet is too high, which is not good from the perspective of geomantic omen. It is best not to exceed 1.5 meter high shoe cabinet. It's no use wearing this curtain. It can be solved by setting a large frosted glass near the entrance of the living room. Staggered bedroom doors 10cm are useless. You can let the younger ones live in the south and the older ones live in the north, which will control them and avoid swearing. You can also hang a curtain at the south gate to melt it.
