My knowledge is ( severely ) limited in this, but . . . pollution, for example
don't really know about sanitation/healthcare etc , I am sure some other threads on here may address this in more depth. Given you live closer than us Europeans, wouldn't a 2week On/2 week Off roster be a better plan ? I (personally ) would have thought so, if you really need to go down this Chinese route.
With the caveat, that I am taking your "Location" in Sydney as being honest. . . . I am (most assuredly) in FUBAR & expect all Peeps to be just as transparent as regards their whereabouts.
