Z visa holders, It expires in Jan 30 but i will like to stay 1 1/2month traveling is that possible?

Tita, I think you meant that your resident permit is going to expire on Jan. 30, right? If so, I am afraid that you need to get out of China to apply for a L type to continue your trip in China. Perhaps, you may visit local entry and exit management bureau to ask if you can apply for a L type without leaving.
