Transiting at Chengdu at mid night

First of all, I'd like to tell that it is allowed to stay overnight there at the Arrival Hall or you can spend a night at a 24-hour cafe or restaurant. In addition, an Airport Business Hotel is located in the east of T2.

However, you actually have enough time to have a short trip in the city. Why not? Take airport shuttle bus to downtown area like Tianfu Square. You can go to Chunxi Road and Panda Research Base. Stay in a hotel in city and take a taxi to the airport to catch your early flight.
