Is there any luggage storage service for 4 big luggage bags at Entrance of Zhangjiajie Grand Canyon?

I remember there is no official left-luggage counter at the entrance, but you can pay a little and store it at a shop or resto nearby. At the entrance of the park, you can buy both the entrance ticket and the ticket for the bridge.

The scenic area is open till 17:00, so you should experience the glass bridge before that time.
