The secret of Taipei 101: There are not 101 floors in Taipei 101

Taipei 101, sometimes stylized TAIPEI 101, formerly known as the Taipei World Financial Center – is a landmark supertall skyscraper in Xinyi District, Taipei, Taiwan.
The building was officially classified as the world's tallest from its opening in 2004 until the 2010 completion of the Burj Khalifa in Dubai. Its elevators, capable of 60.6 km/h (37.7 mph) used to transport passengers from the 5th to 89th floor in 37 seconds, set new records. In 2011 Taipei 101 received a Platinum rating under the LEED certification system to become the tallest and largest green building in the world. The structure regularly appears as an icon of Taipei in international media, and its fireworks displays are a regular feature of New Year's Eve broadcasts.
