There are two ways to choose. The first one is Lumo Road to the south, and between a construction site in the east of the road and a Yonghe soybean milk shop is Huake Ximen. After entering, you can take the school bus at the south gate, and the other road is the northwest gate of Huake, which is Dadong Campus. After entering, you can find an intersection and ask the way south. In addition, it seems that there is no campus building in the School of Optoelectronic Information, and the current office is Nanyi or Optoelectronic Laboratory.
