Do I qualify 144 hour free transit?

Hi I'm wondering if I will qualify for the 144 hour free transit? If not will I qualify for the 3 day visa free? My flight will be EUG Eugene->SFO San Francisco International->SFO San Francisco International->PEK Beijing Capital->
PEK Beijing Capital->
SZX Shenzhen Bao'an International (5 hour wait in airport)->SZX Shenzhen Bao'an International->SYD Sydney.

Thanks
