USA to Tokyo for 3 days then fly to Shanghai for 4 days and then fly to Hong Kong then fly to Austra

Can I receive the 144 hour free transit coming from the USA to Tokyo to Shanghai and stay 4 days in Shanghai then fly to Hong Kong and stay there for 3 days the fly to Australia then back to the USA. Do I need a visa that's longer then 144? Any in-site or suggestions would be very greatful.
Thanks
Jack
