Passport Renewal Dates conflict with Z Visa Renewal dates.

Hello Every one... My Best Greeting for you all...

New Rules for renewing Chinese Visa here in my City is: this time: Extension must be applied 45 days before it is expired.
And my Z type will expire on 08 DEC 2016.
While my Passport is going to expire on 13 May 2017
As per my knowledge, someone can renew his passport 6 months before it is expired.
So, When I am asked to submit my Z type renewal on about 22 October, my passport will be still valid 7 months and 23 days (only, not enough to get one year renewal).
It means: I am in big problem. Neither I can renew my Passport, Nor I can get renewal of my China permit (one Year Validity Z catagory).

If some one, kindly suggest me what to do? I welcome your advises... Thanks in Advance.
