Hi Jean-Baptiste, Because you don't reply my last message, I guess that you are not agree to move it(them) back.
I've sent a mail to trans-zh_CN mailing list to tell the contributors to pay attention to not spend their time on the wrong project(s). I hope this would avoid the further trouble.
Furthermore, could you please lock the corresponding fedora-website project under zh_CN language in weblate, and lock the nani, rpm projects under Simplified Chinsese(zh_Hans) too?
