In addition to its height, there is also its shape, said William Patterson, president of KPF, the financial center's design was originally inspired by the traditional Chinese cultural understanding of "heaven and earth", which is the meaning of the circle of heaven and earth. Moreover, the 50-meter diameter "round hole" is not far away from the "Oriental Pearl Radio and Television Tower" the size of the second ball, hollow hole and solid sphere just to form a virtual one, echoing the artistic beauty. But such an idea in the eyes of some people, at the same time also showed another image, the first people use superstition to create momentum on the Internet, pointed out that the roof of the large round hole, far from looking too much like the Japanese sun flag. Because many people in Shanghai and China thought the original design looked like two Japanese swords holding the Hinomaru in the Japanese flag, and the builder was even a Japanese company, so they put pressure on the Shanghai World Financial Center Corporation, and even some people boycotted the establishment of the World Financial Center.

The center company then updated its design, replacing the original garden hole with a square hole. But most people who don't hold this view think it's just nationalism through and through. Some thought that the original round shape was more aesthetically pleasing, and that the shape was in keeping with the aesthetics of simplicity and streamlining, and that it harmonized better with the surrounding buildings, such as the Oriental Pearl Tower and the Shanghai International Convention Center, which were also designed in a spherical shape, and others thought that a rectangular shape was not a bad idea, applying the traditional concept of "the circle of the sky, the square of the earth".
