Regarding the application for state aid, generally speaking, if your family's financial situation conforms to the relevant state aid policies, you can consult the local civil affairs department for details of state aid. In addition, in the process of enlisting, you can also consult the military service organs or the army about relevant policies and procedures.
Please note that due to changes in regions and policies, the specific application process and requirements may be different, so it is best to consult the local authorities to understand the specific situation before applying. Good luck!
