Named "German-Chatting-Group". It was not a bar, but a qq group. In this group everyone was only allowed to chat in German. A few years later I was busy and had no time to manage, so I selected a new group owner and transferred my group to him. But at the end that group was dead, because the new group owner didn't want to manage any more. And qq-group is a very sealed-off platform. A group can not let people join this group any more when the owner is inactive. If German-Chatting-Group was not a group, but a bar, it would perhaps not be dead
