They didn't inform me that after-hours self-service pickup wasn't available.

This rental company closes in the afternoon, so we couldn't get the car the same day. We had to take a taxi to the downtown hotel, which cost nearly 2,000 yuan round-trip and was hard to find. It took over an hour of walking and taking a taxi to locate it. Don't be tempted by the low prices; it's better to choose big brands like Avis. Also, their cars are not owned by them but are in collaboration with big brands, prioritizing their own customers' reservations.
