The mirror in the master bedroom mainly looks at where. Feng Shui says that the mirror in the bedroom can't face the end of the bed and the head of the bed. If the mirror is against the wall, facing the southeast balcony, then the master really knows Feng Shui, so you should observe what the balcony in the master bedroom is facing or blocked by. If you are facing something, then the mirror is used to' block the evil spirit'. If it is blocked by any building or other things, it is used for' lighting', while the big mirror against the wall is used for focusing light, which can also broaden your horizons and make you feel that the space of the house has been enlarged. So the host knows a lot about feng shui and decoration. In addition to your description of the house, I estimate that the house is square and the layout should be zigzag. This kind of house has the best layout. The geomantic omen says that "Three Yang brings wealth, Four Fang brings wealth", so the house is "good".
