My go-to is an arch container just because I like to have rolling releases, access to AUR, and I like pacman. I wouldn't overthink it though. If the fedora container works for you, then it's fine.
Get a VPN (I can personally recommend LetsVPN or Astril, both are good) or if you get a HK sim, an esim like holafly, or a roaming plan for your current sim you should be able to use your data without being subject to the great firewall
If you have an iPhone then apple maps is pretty decent, Baidu maps is better but in chinese only afaik
Get a payment app. I used Alipay as it accepts overseas cards but I think WeChat accepts them now too.
Download WeChat anyways because its so useful and you never know when you might want to add someone
Make use of the conversation feature on google translate and make sure to download the language packs in case you donât have internet for whatever reason
Tachiyomi was so good that I literally kept my old android around only for that app.
Suwayomi still exists but it relies on Tachiyomi extensions so I don't know how useful it's going to be going forward.
Frick Kakao!!
