The Chinese New Year - 8th of February 2016. For how many days the Pakistan embassy will be closed?

Hello everybody,
My name is USMAN. And I am a Foreign International Student in Hunan University since 2011. I just finished my graduation in Computer Sciences last year in June 2015. And Now I am studying Chinese language there for 1 more year.

Unfortunately , my passport is going to get expired by February 2016 - last week.
And I need to go to Beijing to renew it.
I can only go there by February 6th.

Can anyone please tell me that for how many days "usually" the Pakistan Embassy remains closed during the Chinese New Year Holidays? And when does it stops working???????

Please tell me ASAP. Its a very very very very urgent emergency!!!!!!. Thank you.
