covid 19 – Possible to play badminton temporarily as a foreigner in East Asian countries during 2021?

I am from Germany and I am wondering about any possibilities to do any kind of Badminton vacation anywhere in Asia during (the first half) of this year. I am saying Asia, because I am assuming that life is normal there in many places, while I am not confident that I will get to do sports with other people this year in Germany. At the same time, Badminton is a lot more popular in some Asian countries, so I am guessing there could be regular training camps.

Of course I am aware that travelling is not the best of ideas at this time, however I am planning for an extended stay, will get myself tested accordingly, and I have also literally not been meeting anybody for months now.

I have been searching on Google, but with little success. I greatly appreciate any help! Thanks!
