According to the national secrecy laws and the superior civil air defense policy documents, the location, quantity and area of civil air defense projects (including air-raid shelters) are confidential information and should not be directly disclosed to the public. If you want to know whether there is an air defense basement near you or where it is, you must follow certain procedures. At present, all the entrances and exits of air defense basements in Tonglu County are marked with air defense basement signs and supervision telephones, which should be easy for residents to identify and know. According to the air defense plan of Tonglu County, there are two main ways for residents to get civil air defense protection in wartime: First, the street community arranges guides (after hearing the warning sound) to lead the people to hide in the nearby air defense basement. Second, relatives, friends or the government are evacuated to nearby towns (streets), and the corresponding towns (streets) are responsible for receiving resettlement.
