Help with shanghai Visa?!

You are not entitled to this Free transit when arriving in Shanghai because Copenhagen-Shanghai-Copenhagen and Paris-Shanghai-Paris are not transit at all. You need visa for the trip or change your flight.
In Shanghai, the 72 hour free transit has been updated to 144-hour free transit.

But can i fly from Copenhagen to shanghai and on my return flight i fly to Stockholm via paris?
My route would be Copenhagen-paris-Shanghai-Paris-Stockholm

Copenhagen-paris-Shanghai-Paris-Stockholm is not a transit, either. So no. Copenhagen-Shanghai-Paris-Stockholm, or Copenhagen-Paris-Shanghai-Stockholm will be fine for applying for Shanghai 144 hr free transit.

Please understand i am flying Copenhagen-Paris-Shanghai-paris-Stockholm but i will only be connecting in Paris i will not go out
I will be flying from Country A which is Denmark to Country B which is shanghai, china and onward to my third country which is Sweden so in Paris i will only be connecting!
Am i entitled to the 144-hour free transit?

No.

I just contacted the immigration in shanghai and they told me that they only count the last flight for me that would be the Paris-shanghai and Shanghai-Amsterdam flight, for example i can fly Stockholm-Paris-Shanghai but not the same route back on the return flight i must fly to another country/City like Shanghai-Amsterdam-Stockholm?!

My final route would be as i mentioned above including the connecting flights in Paris and Amsterdam

Stockholm-Paris-Shanghai-Amsterdam-Stockholm

Do you think this is the right way and am i entitled to the 144-hour visa if i fly this routes? just double checking with you ?!

Thanks

Any Country > Paris > Shanghai > Amsterdam > Any Country = ok

Any Country > Paris > Shanghai > Paris > Amsterdam > Any country = Not allowed even if you don't leave the airport in Paris.
