I specifically chose a rental company with Chinese language support because, although I can handle basic English communications like ordering food or booking hotels, renting a car involves signing a full English contract with lots of details and technical terms I may not understand. A fully Chinese service process is crucial for avoiding misunderstandings. However, both pickup and dropoff services were in English. I even asked if they had staff who could provide service in Chinese, but the answer was no. While the rental process was smooth, the lack of Chinese service was still concerning.
