Robert Walters has a 2014 Chinese Salary survey on line. The salary range for a CFO is 1.5m to 2.0m RMB"

"Her salary should be $150k its 10% of that."

"I pay them 20% less than here in Aus."

We can deduce from the above statements what you pay your staff. And that Sunbridge pays 10% of what it should be... therefore in fact you are accusing Sunbridge of paying exploitative wages (after all, if paying someone 10% of their worth isn't exploitative, then what in your opinion constitutes such?)

I provided you with the reference studies that give an idea of what executive level positions are paid in China... and Sunbridge seems to fit in the middle somewhere.
