Having spent several years in Chinese supply chain activities, the factories building iPhones, XBoxes etc. Are some of the nicest ones around. Clean, large campuses with organized activities for workers etc.

There are several tiers of factories below that, with worse worker accommodations, Longer working hours, worse working conditions. Some of the smaller, poorer factories will provide little in terms of personal protective equipment, ergonomics, and make stuff for the local, African and South Asian markets where there’s little pressure on companies to have a “clean” supply chain. These workers would go there.
