Tsinghua University Auditorium and Library.

The lawn in front of the Tsinghua University Auditorium is still green in the winter. The leaves of the locust trees and paulownia trees have already changed color, but the strong northwesterly wind has not yet arrived, so only some of the leaves have fallen. The grass, trees, buildings, and roads form a harmonious picture with different colors, and it is difficult to capture the effect with a phone camera. Behind the auditorium, separated by a river, is the Tsinghua University Library, with the old library on the right and the new library on the left. The old library is nearly 100 years old, while the new library was completed in the early 1990s. The two buildings blend together seamlessly, and the library has won many national awards for outstanding architecture.
