Qualified route for 144 hrs entry permit?

There are no direct flights to Shanghai from the airport closest to me, so the route I've planned is Hamburg - Amsterdam - Shanghai - Paris - Hamburg. Will it qualify for the 144 hour visa free transit, even though the flights from/to Hamburg are only layovers (as in I won't be entering those countries)? Or will it be a problem when I'm a German citizen but enter China from a "foreign" airport?
Thanks a lot!
