1. The law stipulates that the civil air defense work is supported and supervised by national laws and regulations, and the relevant laws do not stipulate that the civil air defense certificate is only used in this province. Therefore, nationwide, the civil air defense qualification certificate is basically universal and can be used in other provinces.

2. National unified management: Civil air defense work is jointly managed by the National Civil Air Defense Office and local civil air defense departments, with the purpose of ensuring the safety of the country and citizens. Nationwide, the standards and requirements of civil air defense qualification certificates are the same, so they can be used across provinces.
