Do you have residence permit in China? or copy? if yes, just bring your these documents to Chinese embassy in Pakistan to apply for a new student visa.

what is resident permit, explain it...i have the scan copies of my last three visas...first one i got from chinese embassey from pakistan and other two i got in zhengzhou university

Is your visa an X? if yes, you are required to change it into a residence permit within 30 days after entry. The residence permit works as a multiple entries visa, with it you can exit and enter for many times during its validity. So, now, if you have not one, you can just bring your copies of previous visas to Chinese embassy. In addition, you need to apply for a Travel Document for go abroad first from your home government.
