China isn’t a great example of this to be honest because they do by sacrificing worker safety, safety regulations and often the integrity of the project itself. Many a bridge built in China was found to have industrial garbage stuffed in pylons instead of concrete, and most buildings only have a serviceable life of less than 5 years. If you want an example of amazing work ethic look at the Japanese digging an underpass under a highway in less than 3 days without closing the highway.
