Introduction to Western-style buildings: The back two entrances are Western-style buildings. The high walls and deep courtyard are self-contained. They are composed of the main building and the back building. The width of the two entrance courtyards is nine rooms and two corridors, divided into two rooms. There are three units in one living room, and the 14-meter-deep front yard is sealed with a 6-meter-high wall. The main building's platform base, steps, wall skirts, door frames, columns and other stone components are all made of high-quality Meiyuan stone. The interior is paved with colorful mosaics decorated with fish scales, with olive branch patterns at the four corners. The materials are exquisite, the workmanship is fine, the lattice doors and windows, and stained glass are all magnificent. It is the essence of the building in the back area.
