Also, the AUD and US dollar could drop to as low as 4 in regard to parity with the RMB, which will be a disaster.

With the skyrocketing prices of consumer goods in China, the 1:4 parity would seem more like 1:2. Recently when I was in china I felt like even though the parity was 1:6 with USA currency: China Currency the buying power was already less than 1:4.

If you want to save money and enjoy your time, think twice before coming to china to work. You will work your butt off if you end up at the wrong location and you will find you cannot buy what you want even if you are in a more frugal mindset. This country just gets more and more expensive to live in by the day.
