Cutting so many corners that you end up making virtually worthless garbage seems to be woven into the fabric of Chinese society. They make their own dams, military ships, military vehicles, buildings, etc in the absolute cheapest ways imaginable. (Have you ever seen counterfeit concrete that's really just garbage bags full of trash? That's a real thing in China.) Sure, they can sometimes make a decent product, but don't underestimate their ability to ruin things.
