Chengdu Guide of places and things to know?

I'll be moving to Chengdu in January with my non-working wife and wanted to start compiling a giant list of useful things

-Things to do

-Places to go

-Places I should know (hospitals, foreign/English speaking dentists or medical places, embassies)

-Apps to download (are these metro/bus apps specific to Chengdu? Mini apps in Alipay?)

-Neighborhood characters, ideal places to work (my work will be in the New High Tech area)

-Places to avoid for whatever reason

I save everything in my notes so everything is appreciated
