Introduction to the Second Gate: The Second Gate of Tsinghua University in Beijing is the palace gate of the "Little Wuye Garden", a royal garden of the Qing Dynasty. It is also the earliest gate of Tsinghua University in Beijing. Since the new gate was later built, this gate was called the Second Gate. The second school gate is located behind the administrative building. It is a scaled-down second school gate to show the continuity between the two schools.
