There's an analogous problem for Russians, and presumably folks from other Slavic-language countries. Our last names are gendered; if Ivan Kuznetsov marries Elena, her last name becomes Kuznetsova. (And their children would have gendered last names, too - little Borya Kuznetsov and little Masha Kuznetsova.)

So Russian families who move to America have a choice - either deal with people and systems who assume that married couples, and parents/children all have the same last name and hit roadblocks when that expectation does not match reality, or change one partner's last name to match the other's.

But that second option has problems too, because that name change doesn't retroactively apply in Russia - so now you might have American documents that say you're a Elena Kuznetsov, but your Russian documents say that you're Elena Kuznetsova - so any legal dealings that involve the two countries (like, say, traveling) become significantly more complicated because you need to prove that the two names actually point to the same person.

At least middle names aren't a big issue - patronymics mean something in Russia, but here in America it's just a string you pop into the "middle name" field, and maybe you get asked what it means, and get to teach someone what patronymic means.

Chinese people rarely change their surnames after marriage; kids usually inherit the father's surname and that's it. This has never caused any issues; systems I've interacted with have been totally OK with the idea that the parents can have different surnames from each other.
