Well, then lets compare apples to apples and take the period after 1990 when China started to approach international standards (I remember scary domestic flights before that time on russian hired tupolews the pilotes sometimes seemed not able to operate properly, sometimes even with russian crew who might or not have understood the chinese air control).

Since then I saw 2 CI planes in the water behind the runway in HK alone.
They were immediately trying to scratch off the logos that one couldn't recognize the airline.
