Zurich to Shenyang (need to transfer in Beijing) then to Singapore

Hi, I am holding Germany passport and will fly from Zurich to Shenyang for 2 days, however, there is no direct flight to Shenyang from Zurich, thus I need to transfer in Beijing airport.

Then after 2 days staying in Shenyang, I will fly to Singapore from Shenyang directly, am I suitable for using the 72-hours free transit??

Thank you very much!
