We prepaid 4653 RMB for the car, but after arriving at the airport, we were downgraded. Later, the battery died, and the car was in poor condition. It was a 1995 car with over 100,000 kilometers. The battery was so old it was deformed. We waited four hours for assistance, only to jump-start the battery. This was misleading and we couldn't continue our week-long trip. Then we were given a small manual car by the repair staff, which was another downgrade. The small car rental was 1189 RMB. The price difference is 3464 RMB. Please refund us. The car rental experience was very poor.
