I would like to post a Chinese job posting. According to forum rules, how to post it is legal
Basically if you want to post a job posting in that language then you go ahead and post it on their local:
Local > 中文 (Chinese)And using the translate to English feature of my browser, this sub is their flea market:
跳蚤市场But I think you do understand some Chinese characters so if your target and potential hirees are Chinese then go ahead in there and then when you're done, as said by Cantsay given the Service section, you can also post it in English language including all the details of it as many Chinese people also do understand English language and might read that thread you'll post there.
