Can I use "144 hours visa-free transit" option at PVG airport 2 times?

I want to land at PVG airport and apply for "144 hours free transit". After 5 days I will leave China and travel to third country. After 2 weeks I want to go back to Shanghai and apply once again for "144 hours free transit" showing my return ticket to next third country, for example:
Europe - Shanghai ( free transit) - Hong Kong - Shanghai ( free transit) - Singapore. Is it possible to do?
