Why can't I book a room at Song Yuan Hotel?

Song Yuan Hotel can't book a room, because the room is full and the system is out of order.

1. Rooms are full: Song Yuan Hotel is a well-known hotel with a large passenger flow. At the time of booking, the hotel rooms have all been booked, which will lead to the failure to book rooms.

2. System failure: In the application of Internet technology, problems such as system crash, network interruption and data processor shutdown will lead to the failure of the booking process, so it is necessary to resubmit the order and make an inquiry.
