Am eligible to apply to the 144 hours visa?

I have a German passport and I'll be going to China for a 5 days. My itinerary is as follows: London-Seoul (there is a connection in Beijing of 2 hours) and I stay for 5 days in Seoul. Then Seoul-Beijing where I stay for 4 days. Finally Beijing-London.

So am I eligible for the 144 hours visa even with that quick connection in Beijing from London to Seoul?

Many thanks!
