Enter before 13 january 2016, but i am travelling on 12 january 2016 from india

Hi
I have M category double entry chinese visa and i have 1 entry left, first entry i used in july 2015.
My M type is expiring on 13 january 2016 and i am traveling on 12 january (i.e. I will be in mainland china on 12 january noon). My return is on 19 january.

On my paper,
Caregory: M
Enter before: 13 jan 2016
Issue date: 13 july 2015
Entries: 2
Duration of each stay: 30 days after entry

Can i go with this M type only or have to apply for a new one?
