Has anyone studied the fire engines?
The two are not the same, a state burden (public security, fire protection), one is the burden of enterprises (enterprise full-time fire), if the consumption is large, to close a certain fee,
Public security fire is absolutely not money, but you say that the military enterprises, residential areas fire, "factory fire engines" refers to the factory's security vehicles or non factory enterprises full-time fire
Also reasonable, if it is the factory's defense vehicles, it should not be charged! After all, it's not a fire enforcement unit!
