What is a hotel room? What hotel in Dalian has zero rooms?

Room zero is the room where you stayed in the hotel around 12 in the morning. Call room zero! Or check out at noon the next day! Because the time is shorter than usual! So the room price is relatively cheap! Many hotels in Dalian have them! It can also be said that almost all hotels have it! For example, the postal hotel next to the railway station and the hotel in Hongfu Building opposite him are all zero rooms! And the price is half of the ordinary price!
