Friendly neighborhood admin here.
The rule in “Learning Chinese” is that ANY Chinese content should be accompanied by some intelligible commentary or translation in English. Think “can someone who doesn’t know Chinese as well as I do make any sense out of those squiggles up there?”
The forum is Learning Chinese. We are (as a whole, not perhaps one particular thread for those who might want to post solely in Chinese) dedicated to making Chinese make sense to people, and those people have English as a shared fluent language.
This is laid out in the pinned thread titled “Please read before posting in 'Learning Chinese’”. It is indeed a forum rule and we appreciate your help with keeping “Learning Chinese” a place where those who might still be in the early stages of their Chinese learning journey can keep up. (Or, really, just us furriners in general. If I ever feel like I get out of the ‘early stages’ of learning Chinese, I’ll let you know. lol)
