You probably tried to write something out of compassion for those tired Chinese workers, but what you actually wrote appear as insensitively dismissive (an average poor guy at an assembly line absolute have abilities to think). And more importantly I don't think it's correct. Most people, even those who do have plenty of spare time, don't dig archeology, or fact-based history that much. History as a part of identity is a different story, and many are very emotionally invested in it, and from my experience in Far East cultures especially so. So 'most Chinese people' may not look interested, but only before somebody tells them they are not that ancient.

I'm glad that the schools are teaching scientific truth then. It doesn't really matter what lineage is older, and the cutoff is arbitrary anyway. But teaching historical facts that disagree with nationalistic and party narratives is a good barometer for respect for science itself, which is very important.
