Proof of Married Name (Shanghai)

We are planning to move to Shanghai from the UK for my husband's job and are obviously having to provide lots of paperwork in connection with this, including my birth certificate, wedding certificate and passport. As I took my husband's surname when I got married Protected content ago) my name on my birth certificate and wedding certificate is different from my name on my passport and I am being asked for some official paperwork to prove these two different names are both me! Has anyone else had this problem and if so can you tell me what you did about it.

Thanks in advance
