A Z visa is only good for thirty days and is only for the purpose of getting your FRP (Foreign Residence Permit) which is what allows you to live and work, as well as enter and exit China at will. You can only get an FRP from the agency that sponsored your Z visa. Your invitation letter has red numbers which match to other part of the perforated document your school holds that prove you are sponsored by them.
You must be sponsored by an agency that is SAFEA licensed to hire foreigners. It is through this agency you are allowed to live and work in China. When you sever this relationship, by leaving this company, you will have your visa changed to a 30 day tourist visa.
As long as you are sponsored by them, they are liable for your misfortunes such as accidents, legal entanglements, etc. Needless to say, your school will not desire to carry this responsibility for someone who no longer works for them. So, when you announce your departure, they will want, and are in fact required, to have your visa changed to a tourist visa.
The visa system in China is similar to that in most countries, it does not contemplate people coming over under employer sponsorship, then dropping the sponsorship and becoming independent operators.
Cheers.
