Can I hang a light box in the office corridor?

The public area is not a private area, so it is not allowed from the ownership, unless you negotiate with the property or the lessor to confirm that it can be done if the other party agrees, but it may cost a certain fee.

Improper feng shui objects are strictly prohibited in the porch of the corridor. If you want the placed feng shui objects to have a good feng shui effect on you, it is best to put appropriate feng shui objects in this porch in combination with your own eight-character and five-element situation, so as to turn evil into good luck and bring auspicious feng shui fortune.
