Wow! I amm very glad to hear that you are working hard and that you have such achievements. It is only because ofyour hard work and being so persistent.
The apartment that you had was very cosy but who knows maybe it is even better that you now moved, electric scooter is very popular here too. People here, especailly young peopple also prefer to take scooter, here you can rent it , there are companies that rent and such scooters parked outside you pay online and can use any to the place you need to reach and just leave it there after.
You definitely need to visit Chongqing once and also to post about that. Watching the documentary the train system and stations were like in Sci-Fi movies. Also it is a reason to meet up with your roommate.
Yes, there is an app that I know
It is Chinese app and you might like it, just try I communicated with their teams in the past when it started that time we organised some contest and Wherein supported them too.
Have a nice week,
