Introduction to the South Gate: The South Gate is located on the first floor below. It has a unique style and adopts the form of Western architectural columns. The shape of the four columns is taken from the traditional Chinese archway, with a traditional Chinese brick and wood structure hall above. The entire south facade is a tall white wall, covered with black tiles, giving a clear distinction between black and white. The flower beds at the base of the wall are planted with bamboos, which is particularly refreshing. The south gate faces Zhongshan East Road, and outside the gate is a small sunken square, connected to the entrance and exit of Daxinggong Station of Metro Line 2.
