If you don't have a credit card or the credit limit is insufficient, you can ask your relatives and friends who have a credit card to vouch for you, reminding you that the guarantor should bring a valid ID card and enough credit cards to pick up the car with you and sign the car rental form. The guarantor will bear unlimited joint and several liability for all expenses and responsibilities incurred during your rental period. In addition, for vehicles with a standard pre-authorization of 5,000 yuan or less, it is not the first time to rent a car, and you can use a domestic debit card to pay a deposit equivalent to the pre-authorization of renting a car.
