Visa still valid on the Old Pakistani Passport, renewing my Passport this Month February 2016

Dear Everyone,

I am a Foreign International Student at Hunan University Changsha for the past 5 years now. I did my majors in "Computer Application and Technology" - Master Degree ; and now I am studying Chinese Language here too. I came to China in the year 2011.

My Pakistani Passport will expire on 4th July 2016 .
And my X type is still valid till 3rd July 2016.
But I will go to the Pakistan Embassy in Beijing to renew my passport in this month of February 2016.

I want to ask that after getting my new passport,
if the Pakistan Embassy cancels my old passport ,
but the X type is still valid, then can I use still my X type on the Old Cancelled Passport?

Please inform me as quickly as possible ; because there is a very critical emergency here.
Thank you.

P.S: I will fly to Beijing on Feb 7th.
