@shortstories Chinese engineering culture was terribly damaged by the cultural revolution which intentionally discarded good engineering practices for an ideologically motivated selection bias towards designs or coat saving modifications originating from uneducated working class people and away from unreliable educated types
For like 15 years they were building things that not only didn't work well, but were frequently unsafe and geared towards mass production while engineers farmed sorghum on a labor camp somewhere
This is all recognized as a mistake now but 20 years after the industry still bore the scars of the bad ol days
