Transit in Shanghai Pudong Airport for 14 hours

Regardless of your citizenship, you have right to transit through China covered by 24 hour visa free transit. Your itinerary suggests that your total transit time that you will spend in mainland China is 14 hours, so you really do not need any kind of visa. However, when traveling on this visa free transit scheme, you can never be certain if you will be allowed to exit the airport. Simply speaking, your right is to travel through China visa free, but the exit from the airport is not a passenger's right.

The experience presents that majority of those who have longer transit times, especially those with 8+ hours of layover, are usually allowed to exit the airport and to enjoy some time exploring the city. In other words, everybody can apply for a temporary entry permit at the transit counter (desk) of the airport upon landing, but not all will be granted a permit. Passengers with very long layovers, especially those with night layovers or with small children are practically always granted a permit. If I may predict the outcome, I would say that your chances to be allowed to exit the airport are really, really very good.
