What does the caller ID Xianheng Hotel mean?

Some hotel phones will be displayed, so you can pick them up and listen to them. If the other party has a clear report, you can call the hotel center later to find out if this is the phone number of the hotel.

As for why the other party called you, you can recall whether you have checked in before and whether you have made a reservation.

Of course, it may be that the sales department is recommending something to you, such as a room or a meeting.
