Sometimes when we think about something that is bad about some Chinese investor, or whoever, we always think of politic, but actually we realy should think of what we had done wrong and what we need to do.  In earlier article, it talked about the SEC and PCAOB is more strick on the rules and more care with the RTO because the current deal with China in regards to the inspection on the WP. It's a long way to go until the sun rise again.

When the country is big enough, she can make rules.

Reasonably,  it concerns with responsibility and something else. But why did such a legal country have no rules to sensor something at first?
When the result is not we expected, we try to find someone to take the responsibility. But why do they want to go publich in US at first, not in domestic market instead?
Then, in the investigation process, someone may be the scapegoat. But if the investors are all good ones, will the mediator be a good person? We don't know. After all, he did a lot in the process.
