Its also on the side of a mountain lol, of course its going to be built that way. I spent about a month there last year and my calves were ridiculously jacked, easily 8000 steps a day if you don't take taxis/Didi since traffic on winding mountains is more roundabout than just taking the stairs. American minds cannot comprehend a city where you can literally walk/metro everywhere you need to go faster than driving.

Edit: Food in Chengdu was better though, Chongqing has hotpot cornered but the variety and quality of more traditional Sichuan food was superior in Chengdu.
