Generally speaking, when you buy a car, you must transfer it to the local vehicle management office for the transfer of the car.
Then you must have a driver's license, and you'd better buy insurance or something.
So you can legally hit the road.
If you buy vegetables from the countryside and resell them to the county town or Xichang and other cities, you generally don't need to apply for any certificates to do wholesale business. Just contact the vegetable distributor in the vegetable market and supply them directly.
If the other party needs to issue invoices and other services, you can ask local farmers to issue them on behalf of the tax authorities, all of which are tax-free.
However, if the quantity demand is large, it is more convenient for you to register your own company or individual industrial and commercial households.
If you want to do retail, it depends on the local actual situation. In the general vegetable market, you only need to pay the booth rental fee to operate directly. If you need to stay in the store, you need to handle individual industrial and commercial households and tax.
Roughly so, for reference only
It's best to ask yourself how local people who do the same business do it.
