The key card cannot open the door of the room, call the public relations, say to hold the card down to the counter below, we come down to send the key card to the staff, the staff says that the key card has expired, send us a new one and then we ask not to send. The staff went up to see? If there was a problem, we had to walk down again, right? He therefore asked the male staff to come up with the final result as we said. It appears that the key card does not have a problem, but the problem is in the key system. The card itself, if we don't speak, probably won't let the male staff come up as well, we have to walk down and walk down a few more times, please help improve the staff, everything else is ok, everything except the receptionist.
