It's not sensationalism or scaremongering. Klughart is correct. You are by no means allowed to work while studying, you can go through the hassle of changing your visa, but you are not allowed to work.
In China there is no study-and-work visa like in Australia, Europe or quite literally, every other country in the world, [another violation of international visa treaties, in Germany Chinese can study and work but Germans not inChina].
I dunno how you did it, maybe your University pulled some strings. But that said, it has nothing to do with your College and even if they told you, that you can, by definition of the law and visa regulation you cannot. Your University has no jurisdiction to decide that [PSB has], you can take their [univ.] documents and run it through the PSB, but they have the power to give you green light.
I know you will not believe me, so just call the PSB on Tudong Lu and they will explain it in detail to you, as they did to many others including me.
YOU.....CANNOT.....WORK......ON.....ANYTHING.....BUT.....A.......WORK....-VISA
The good news though is since my first arrival in China in 2001, there were words, to change the regulation, and it's already 2016, just a matter of hours until we can work and study here.
Nuh, it's much more fun and powerful to let Laowai's stumble into illegality. So you can fine, deport, or squeeze bribes out of them, [which happened to 3 of my friends in visa happy 2008. The cop made 12000RMB in 30 minutes, and that only in their shared apartment].
But yeah China is awesome!!!!
