Very easy to find, the stores all have Hertz's yellow signs. The previous blue ones seem to be out of business.

Once you exit the terminal, follow the signs to find the store. There are many people, and you will need to wait in line. You should be able to communicate in English.

The service was quite good.

There was no mention of this during the booking. It wasn't until I saw the charge on my credit card statement that I found out about an extra fee of around 100 yuan. After 10 days of inquiry, the car rental company claimed it was a special location pickup fee. They couldn't explain what constitutes a special location. I picked up the car at the airport, which I guess is pretty special! It feels unfair, even though the amount isn’t much, it's still frustrating. Seems like I need to understand the rules better next time.

They asked us to buy additional insurance and a full tank of fuel, but didn't clearly explain when we were signing and paying. We only found out from the credit card bill after returning home. Very frustrating.
