How do you say "Do not disturb" on the door of the hotel room?

privacy

Renjunrich was right, but we should pay attention to the technical difficulties. It should be noted that this is hung on the lock of the door, which is very close to the door. Excuse me is too long. If it is Do Not Disturb, it is written as follows:

(Please)

Defense Order (defense order)

no

hinder

Most hotels use (please) Do Not Disturb, which is also useful for privacy.
