tourist visa

I am in china right now on a tourist visa. I have applied for a 30 day extension before the 60 day extension was given. Now the 60 day extension is almost up. Now the psb tells me that I have to leave to go back to USA. All the flights are cancelled and I can't do anything really. I had a friend apply for another 30 day extension once they showed flights are cancelled. It cancels your tourist visa though. I want to know if there is a way to extend my stay in china without going back with another kind of visa?
