Is The 72h visa ok and where do I asked for it, at PVG airport?

I'm a flight attendant from Switzerland and like to take my daughter whit me on my Shanghai trip. Arriving from ZRH at PVG on the 29.5 7.30 and living PVG to ZRH the 31.5 at 9.30. May I take her whit me on a 72h. transit and where can I asked for it? At PVG airport or in Switzerland?
Thank you. Greetings Béatrice
