you can find the two largest listed car rental companies in China (the specific names are not mentioned to avoid advertising). Now, you can see the models and prices through official website, mobile APP and other means, which is very convenient.
generally, you don't need to pay a deposit for renting a car, but only pay a pre-authorization, and you can unfreeze it by returning it. The credit card amount required for renting different models is different. In principle, the more expensive models need the higher amount. Car rental fees mainly include handling fees, insurance fees, car rental fees, etc., and overtime fees, off-site return fees and so on may also occur according to the situation. Returning a car generally requires pre-authorization for violation of regulations. If there is no violation, it will be automatically thawed. If there is violation, you need to handle it yourself.
above, it is recommended to place an order in advance, and then pick up the car at the store according to the order time. Generally, you can complete the formalities and take the car away in a few minutes.
I hope I can help you.
