This is excessively cherry-picked, and I’m just going to steal a quote from Wikipedia to illustrate:
> The Chinese have different languages in different provinces, to such an extent that they cannot understand each other.... [They] also have another language which is like a universal and common language; this is the official language of the mandarins and of the court; it is among them like Latin among ourselves....
The idea that you could transplant a peasant between millennia in China or even over any significant distance, and have them remain intelligible is simply untrue. In addition, you could take an educated person in most of Europe in the last 2000 years and expect to be able to communicate with them in Latin — it’s only the last hundred years or so when this has fallen out of favour. So recently in fact that nobody raised an eyebrow about the fact I had mandatory Latin lessons from the age of ten at my school, in the 90s.
Dialects are overplayed outside of china. Most average people can speak 2-3 just as part of growing up. Learning a new dialect is considerably easier than a Spanish person learning Portuguese or the nordics learning the other languages from the region.
For starters the written language is essentially the same between the chinese dialects - so learning a new one is mostly an exercise of mapping sounds and then learning new idioms. Passing as a native speaker though will be harder as the canto/mando split highlights.
You're right - latin's influence is still amongst us. Indeed I believe it was common to teach Germans Latin in the hope it would make them have a stronger technical appreciation of German. And the UK legal system has its roots in the Roman legal system.
That said I assure you Latin the language is far more arcane than the standard Chinese. Meanwhile in China, suntzu bingfa will be learned and referenced in culture and people have statues of zhugeliang and guanyu in their homes displayed at chinese new year. I haven't met a friend yet you has an Aeneas or Caesar displayed in their house.
Maybe Hercules and Zeus as figures are more prominent examples of people we have remembered but they aren't really celebrated in that first hand nature. I don't think Brits identify with Hercules or even Boudica. But I would posit chinese people do identify with the ancient greats like kongzi.
EDIT
I think the idea of identity is key. Interestingly the Chinese people in Singapore and Malaysia diverged from China ~150-200 years ago. But this sense of identity with the old chinese history has been preserved between both of them so you can't just write this off to CCP propaganda.
Perhaps culturally Chinese culture has always sought to unify/assimilate things into its monoculture whereas the history in Western europe has been a more fluid and accepting melting pot.
