PASSPORT INQUIRY for applying china visa

Hi, I was married last year and my passport still bears my maiden name. do I have to apply for a new one since we will be applying a tourist visa? My passsport expiry is on 2013 (with my maiden name). All my ID's are now being updated with my married name. Can I just attach a marriage certificate to support my claim? Will I encounter problem with my visa application, since other supporting documents and IDs bears my married name?

Please revert to me soon as possible. Thanks.
