Being vulnerable while describing fatal errors while functioning within a hierarchy is very dangerous.  There is no safe way to do that.  If you have not done so, consider reading Richard Feynmann's account of his participation in the Challenger Commission.   Had he not been a famous Nobel Prize winning physicist, and described the exact same set of facts, he may not have come through that experience as a hero.  In the US, hierarchies exist and it is human nature to fear them even if they are not as obviously brutal as those in mainland China.
