How to find a job as a general worker in a Shanghai factory without going through an agency? Thank you.

Did the poster come to Shanghai from other places to look for a job? There are many intermediaries outside now, and they will usually ask you for a fee. If it is a large website, the success rate is probably lower because the requirements are very high. I recommend you check out Yinling.com. There are many job recommendations out there for moderately demanding jobs.
