To pick one example, OP talked about meituan like they haven't seen multiple meituan delivery riders per block every time they take a walk. It strains credibility. Why do they even know the name if they don't see that? Its not like they operate in America.

We're in the age of the Internet. You don't have to be physically there to see anything. They could have just read it on the news, saw social media videos, etc?
