Hi. To select the language go into Tasker > Menu > Preferences > UI > Language (at the bottom).
Edit: I've tried fixing the chinese translation. Is it better now https://www.dropbox.com/scl/fi/gyxfw8kimxyb0b1d1yaqu/Tasker.35.apk?rlkey=yacgs4ykb5c3rxb1wgn46a6oa&dl=0
Edit: let me know if the translation is better! Thanks!
