Tetraphobia

- Tetraphobia is an aversion to or fear of the number 4. It is a superstition most common in East Asia. In these countries, these floor numbers containing the number 4 are often skipped in buildings. In Hong Kong, some apartments such as Vision City and The Arch skipped all the floors from 40 to 49. Immediately above 39 is 50, leading many who are not aware of tetraphobia to believe that some floors are missing. - from Wikipedia.
