Shaped like a dragon -- and stretching the length of seven football fields -- is a colossal row of five stone buildings. This tallest portion is the office tower that looks like a dragon head overlooking the Beijing Olympic District. The last building - the "tail" of the dragon - will be one of only two seven star hotels in the world. The large LED screen is also China's tallest with 900 square meters and was used to live broadcast the Olympic Games.
