Hi, I will be flying from Sydney to Shanghai arriving 7pm, then need to join a tour group at 9pm same day at Pudong Airport to fly to Europe (flight to Milan is scheduled for 1am next day). WIll there be enough time for me to checkout of customs and join my tour group at 9pm? On my way back from Europe I also want to stay in shanghai for a week before flying back to Sydney. Is single entry visa to china sufficient for my entire trip?
