Have a multiple entry visa that we used earlier this year to visit China.

Now looking at a cruise that visits PRC. The Majestic Princess will make its final stop in Shanghai on 2017 July 9. I understand that our passports need to be valid for 6 months following the expected departure from PRC. Allowing for a stay in PRC of 2 days following the cruise this means that our passports would be valid for 195 days after our expected departure and thus meet the 6 month threshold. However, this depends on how this validity is calculated. Could you please verify for me that our passports would indeed meet the required 6 month validity in this circumstance.
