Your statement here is pretty ironic.

China also has many different cultures, languages and so on for the over 1.4 billion people who live there. Why would the “nuance” of Europe be “lost” on a Chinese person?

China mostly has a single national identity, and provincial differences are way too nuanced to be mapped in the same way that country differences in Europe would be. It would be like trying to get Americans to understand that "Henan man" is a meme similar to the "Florida man" meme.
