Introduction to the guards in Space City: Dongfeng Space City is slightly different from ordinary small towns. These differences are mainly reflected in the following two aspects. The first is that the living area and scientific research area are strictly separated here, and outsiders are generally prohibited from entering the scientific research area. The second is that the staff of the city’s industrial, commercial, taxation, water, electricity, postal and other departments are all military personnel. These guards and soldiers guarded the small town and formed a good custom of "not closing the house at night and not picking up lost things on the road".
