The construction of this building has gone through several periods, it has also been suspended as the result of the international financial crisis. In February, 2003, when the building is again under construction, other two skyscrapers measure 480m high were being built in Taipei and Hongkong, however, the initiative of building the tallest building remains in the architects' minds, they redesigned the building, add another seven floors to it, which resulted in the appearance of a 101-floor building with another 3 floors underground that we see in Lujiazui, Shanghai, China today. The height of 492.5 metres marks the 3rd tallest building on earth, the 2nd in China and the tallest flattop skyscraper of the whole world. The sightseeing heaven pavilion on the 100th floor is a 55-metre long corridor hanging in the air. Stepping on this highest sightseeing equipment on earth, one can totally experience the feeling of "When shall I reach the top and hold . All mountains in a single glance?"
