The store was terrible; they seemed to give Chinese customers a hard time. The Chinese person in front of me also had to pay extra. They refused to accept Chinese translations, KIDA international driving permits, and the international permits provided by the rental platform. It wasn't an issue with the translations but rather their way of forcing you to buy full insurance. If the license was not valid, they shouldn't have rented the car to us. However, they required us to buy insurance after renting the car, indicating that they lure customers with low car prices on the website and create various issues during pickup. I often rent cars with an international license in Europe and the US without problems. In Germany, I've never had issues with other companies, but this store caused trouble the first time I tried to rent.
