When I check in the hotel, hotel staff has explained to me it is impossible to use all rooms today. Impossible to check in because Taiwan government will come to survey, not let guests go into the room.
So I was not able to stay the hotel that night. Hotel manager has arranged the another hotel near HaoZhu Inn. And the extra fee was covered by them. So there was no problem at all, but I was very surprised, such issue was the first time experienced for me at the Taipei Hotel.
Thank you for the staff kind conclusion.
