Can I put the piano by the north window?

Of course.

1, the piano is in the north bedroom. Feng shui is good, the piano belongs to gold, and the feng shui should be placed in the west, or in the southwest corner of the northwest, and try not to face the door.

2. On behalf of the second son in the family, placing a piano with five elements of gold in the north is not only conducive to the prosperity of the north, but also conducive to the interpersonal relationship of the second son at work.
