I recently moved into a new apartment (pictures to come) and I have to take an elevator to get to my 20th floor room. Look carefully at the picture of the buttons in the elevator. Is something wrong with this picture? There is no floor 4 or floor 14, but they are instead replaced by 5A and 15A. The reason for this is that the word for four very closely resembles the word for death. So, in superstition, four is a very unlucky number. Kind of like how some elevators in the west don't have 13, but they take it much more seriously here.
