Nope.

I think it's an irrelevant question, tho. There is no evidence that a random Chinese resident would know any more about Chinese corruption than someone with decades of industrial experience interacting with Chinese suppliers, competitors, and coworkers, as both an internal auditor and tester.

I have a question for you:

Do you have any evidence to the contrary? Do you have proof that Chinese national statistics are reliable, and that the supply-chains and all levels of government are generally honest, efficient, and free of corruption?
