Tokyo- Shanghai - Munich

Hello,

I would like to apply for a 72 hours transit visa in Shanghai. However I don't know if it is possible because my flight schedule are a little bit complicated. I intend to fly from :

1. Flight : From Tokyo to Shanghai with Macau Airline , layover time 50 hours
Departure: Tokyo on Feb 12th
Transit: Macau on Feb 12th - Feb14th
Then fly to Shanghai

In Shanghai layover time of 25 hours

2. Flight: From Shanghai to Munich with Turkish Airline
Departure: Shanghai on Feb 15th
Transit in Istanbul on Feb 16th
Arrival: Munich on Feb 16th

With this flight schedule is it possible for me to get a free transit in Shanghai? Is it possible even though I use different airlines? And if yes, can I apply it directly on the airport? How much time does it take? Or can I apply it in advance?

Thank you very much for answering in advance.
