The staff handling the car pickup and return didn't speak English well, explained poorly, and just nodded to everything to finish the process quickly. Most of the promised terms were not fulfilled. On the first day after picking up the car, the AdBlue warning light came on (a fluid additive required only for diesel cars). Customers had to pay out of pocket at a gas station to refill it. Although the cost was small (around 20–30 RMB), this should entirely fall under the car rental company's maintenance responsibilities.
