The appearance of Tianjin Binhai Library is very interesting. Standing not far away, you can see that the entrance is like an oval opening, like a huge eye, so some people call this library "Binhai Eye". The reason why Tianjin Binhai Library is called "Eye of Binhai" is that it is a spherical multi-purpose hall inside. A dome theater is built outside this spherical multi-purpose hall, and the center of the "eye" is a mirror lecture hall, which can directly view the 360° panorama of the library. The interior design that revolves around the "eyeball" is extremely attractive in the setting of bookshelves like terraces, which are both bookshelves, stairs, and seats.
