The documentary is about Shanghai World Financial Center(上海环球金融中心), a supertall skyscraper under construction in Shanghai. The video introduction says that “Ironically, the tallest skyscraper in the world is named “World Financial Center”, resembling WTC in New York so much, but located in the City of Tomorrow: Shanghai. But this building is designed exactly to avoid the same kind of fatal attack that failed the WTC.” (Tip: the video is not complete)
