Gong Zi Ting, the main building inside Tsinghua Garden, resembles the letter H (or the character gong) when seen from above. Since 1949, Gong Zi Ting has been the workplace for the university’s presidents and administrators. Together with the magnolia trees in the yard, the unadorned board has greeted university presidents, academic masters, and dignitaries from around the world. It is like the witness and narrator of many great stories here.
