Clothes hangers on the roof prevent others from using them.

Of course. Because the clothes hanger belongs to your own private property, others need your permission to use it, and it is also your right to disagree.

Before going to bed, lock the door and twist the lock. Prepare another hanger, hang the hanger upside down on the door handle, and lock the groove on the head of the hanger.

In this way, the anti-lock on the door will be firmly stuck by the clothes rack, and it will not be distorted no matter what method is used outside, thus playing the role of anti-theft.
