resently im holding z visa here in beijing but i want to establish my own business here can i renew my visa by my self?

Have you got your residence permit in Beijing? China Z visa expires once you get a residence permit and it can not be extended any more. If you want to establish your own business, you need to apply for a business visa and follow the procedure for the company registration afterward.
