Please don't disturb the hotel room, please clean it immediately. What is the line of the doorbell?

There are usually two ways to connect. One way is to ring the doorbell switch when "Do not disturb". The other didn't ring.

Let me give you the route map. Figure 1 is ringing, while Figure 2 is silent.

Not disturbing is a kind of rest. You don't need to clean and don't let others disturb you casually.

Please clean it up immediately. It means cleaning.
