I am E/F bilingual. I taught in an educational institution which is multicultural with dozens of cultural origins. When I get names wrong, I see grimaces on their faces. When I hear other people get common but foreign names -- like Nguyen for instance -- wrong, I grimace too. I am now at an institution in a country where basically no one outside the country knows how to pronounce anything.
It takes me about 5 minutes to Google names I'm unfamiliar with before I start a new class to make sure I get it right. I don't know and I should not be expected to know Chinese, but I think I should be expected to be polite enough to try to get it right before I take a stab and butcher someone's name.
I don't think it is an enormous burden to put on myself, and I don't think I'm performatively self-flagellating by doing it. I think it's just me trying to be polite. I think everyone should try to be polite in as many contexts as possible.
On another context of names:
My own names are Hebrew and Germanic respectively, two syllables each. My given name is common in North America. Most people pronounce it wrong anyway. I would greatly prefer if they didn't. It's a little disrespectful. I politely correct people and then find most of the same people make the same mistake again and again. I find it disrespectful, the same way I find it disrespectful if someone spells my name wrong even though my email address is first@last. It's not because they're frothing at the mouth racists, it's because they're minorly inconsiderate.
My wife has a common name with two English spellings (let's say similar to Meghan/Megan). People frequently misspell it. She's not bothered by people guessing wrong. She is bothered when she corrects them and they still get it wrong. When I met her, it's not like I cosmically knew which of the two spellings was correct. I simply learned which of the two spellings was correct. It was a basic act of politeness and care. When people don't do it, it comes off like they don't care.
