About the law-annoying neighbor janitor

You can go to the property management company to complain to the doorman, because according to the property management contract, there is no restriction that you must come back before 12, and you will not open the door after 12. Besides, you have already paid the property management fee.

You can put pressure on the property department through the landlord and ask the landlord to help solve the problem.

The last resort is to change another house, out of sight, out of mind.
