I can confirm that Chengdu is a very cool city. Also extremely safe. So safe, in fact, that it wasn't uncommon to see young kids running around this city of 14 million people without parents at 9 or 10 pm.
That struck me in so many places in China, like you'd be eating dinner on the street at like 10pm and there would just be smol children bumbling around doing kid stuff and any time one of them looked to be blundering in the direction of danger a random adult would just scoop them up and point them back in the direction of safety.
I'm tired of hearing "china numba 1" jokes over the years, but it really is (or was, it's been a while since I visited) my fave developed nation. Not a utopia by any stretch of the imagination (I'm always on the lookout for griminess cuz that's my aesthetic) but yeah, just.. really cool. Vietnam and Laos also compete hard for favourite places on earth in my mind.
We've been here for about 3 months now, and we're liking it a lot. We're right off line 5 in an area with a lot of green spaces and some really good food all close by. We saw the pandas a little over a year ago when we came here as tourists for the first time, but we plan to go back again soon now that the weather is really cooling off.
