Switzerland To Germany via Beijng: can use 144 hour transit visa?

I am flying from Amsterdam to Beijing, with a transfer in Switzerland on to way there and a transfer in Germany on the way back. I will stay about 4 days in Beijing. So I will have 4 boarding passes. Technically you could see this as a trip from Switzerland to Germany with a transit in Beijing, but it would be a bit bizar.
Would it be allowed?
