Literally none of what you said is true. Chinese people regularly interact with people of other countries on the global internet. its Literally impossible not to run into Chinese netizens on any major social media site.

You can literally just make an account on Xiaohongshu and chat with normal people in China.

I routinely swap recipes, talk about video games, new tech, swap cleaning tips, chat about restaurant recommendations and fashion. There's a big cultural difference, sure, but Chinese people are, on the whole, incredibly friendly and hospitable and they're curious about breaking down the myths they've heard about America and happy to break down the myths we've heard about China. We think they have a social credit system and they think a dishwasher can afford a huge "villa". Though now that it's opened up a bit they talk about a poverty "kill line" where if you fall below a certain income you are pretty much doomed to die. Which is exaggerated, but has some basis in reality, like most of these myths.

The one thing I think is a huge barrier is that they can't understand why we drink cold water, even in the winter. So many conversations I've had have been about drinking cold water and asking "don't you get dampness???" Honey, I've either never had dampess or I've been damp my whole life so I don't know.

Either way, they're just, like, people. And thanks to the magic of the internet, you can just talk to those people.
