How to get a new M or family chinese visa for French passport?

Dear sir or Madam,

I am living in Shanghai for almost one year and I have a M type, multiple entry, 60 days stay, made in Hong Kong.

I got married in Shanghai last year, at the greek consulate as my husband is greek and has also a M type, same as mine.

I ve contact the agency in HK to renew my M, but they said that this M type for French passport is no longer available, they cannot even do a 6 months one, i have contact also other agencies but i got the same answer.
Some of them told me to try to get it done via France, but as I am not employed anymore by a French company, cannot get this M from France.

I am really lost here and don't know how to renew mine, do you have any solutions/advices/suggestions for my case? Thanks in advance for your feedback,
Nina
