This piece may not be easy to collect in the past, so it is estimated that only cars are accepted. In addition, this tax must have a good relationship with the transportation department, and motorcycles are not easy to count. Now motorcycle management has probably been standardized, so it is now generally accepted.
The tax department belongs to the administrative organ, and the money he collects can't be moved, especially the tax, which must be turned over to the local treasury. Otherwise, none of the taxes collected by the bureau can be collected from the leaders. The so-called tax bureau has no money to spend, and it is sheer nonsense to find a reason to collect money, just the unintentional words of ignorant people.
Local taxes are collected for local governments, and the invoices issued have the same legal effect.
