My flight NY(JFK)-Shanghai(PVG)-Korea(TAE)-Shanghai(PVG)-NY(JFK)

I am flying from NYC to Shanghai (pudong) on 6/16 and I go to Korea on 6/21. So I am staying in SH and Jiangsu for 6 days. Am I qualify for 144 hours visa? I have US Green Card (Permanent Residence card) and Korea Pass Port holder. And I also come back from Korea to NY through the Pudong with 6 hours layover. Am I qualify a 24 hours visa for this too?
