Is there any option that i can get permanent residence that can valid updo long time (5/10 yrs)?

Hi,
I am living in China since Jun-2006, I have been here on "Permanent Residence Permitt" which always is granted for 1 year & every year i need to apply again to get new permitt. My purpose of residence mentioned on the sticker (VISA) is Employment. Is there any option that i can get permanent residence that can valid updo long time (5/10 yrs). I check from Internet there are some options to apply for CHINESE GREEN CARD, is it easy to approve.

I am a Pakistani national, pls remeber

please assist ! thanks
