Inquiry on Visa Requirements for Shanghai Layover

I just wanted to add that my layover in Shanghai is 10 hours. I believe that, as a German citizen, I may be able to leave the airport. Unfortunately, I am not sure about my mother, who holds Peruvian citizenship.

Actually, both of you do not need any kind of visa because you can visit and transit China absolutely visa free and your Peruvian mother will be covered by 24 hour visa free transit. Please, note, this is not 24 hour free transit visa, but 24 visa free transit or in other words, there is no visa at all of any kind.

This is all very simple. You will not say anything at check-in in Frankfurt, but you will tell for your mother that she will travel to Thailand visa Shanghai using 24 hour visa free transit. After a short check, you will be both in the plane. Upon arrival in Shanghai, you will approach visa free transit counter (desk) where your mother will apply for a temporary entry permit. This permit is necessary to be allowed to exit the airport. This application is for free. You do not need that permit. After the permit is granted, you will proceed to the immigration and then exit the airport to shortly explore Shanghai. Basically, this is it.
