I'm not a pilot or related to the industry other than as a passenger (who flew Shenzhen Airlines last week...).
I don't know what the falsifying was but - the Chinese authorities have caught the people concerned and they are we are told undergoing testing and retraining. And it has been reported - so - it ain't all a 'typical Chinese' type thing is it?
Unfortunately not just in China - but if you think of all the emails offering qualifications for money - there is a culture of falsifying qualifications whilst wrong people often feel the need to falsify because bumping up the amount of qualifications needed to get even to the interview stage is used as a way to cut down on the number of applications received.
This problem, it seems to me - has two sides to it.
