Nowadays, electric cars are people's means of transportation. Want to buy in the community, how to pay? If you post it, you have to come from the outside. If you don't let in, you have to post one. Not enough. Tell me foreigners don't have to get on electric cars. If the people in our hospital are in a bright state, they will not be allowed to go back and forth. It's also inconvenient, so this kind of thing is not easy to manage.
