how many 72 visas in one journey?

what about if i fly from MACAU to SHANGHAI staying there with a 72 hours free transit -from there to HONGKONG-from HK to TOKYO-and back to SHANGHAI to stay there with a 72hours free transit-then fly back to switzerland,is that possible?

im not sure if they renew my entry permit,so that would be the planB. but i dont know how many times "in a row" u can use my entry permit &if macau/HK is the same "region"¬ usable as two different countries for the three country rule...
