Business Visa and Temporary Residence Permit

Hi I just have a question about Business visas and temporary residence permits.
If I enter China on a business visa, what kind of residence permit can I get? There's a permit for students and people working in China, but what about people doing work internships? Or is it the same permit as people on the Work visa? And how long would this permit be valid for?
Sorry for all the questions and sorry if this has been asked before!

Thank you very much for your help!
