The order thing is very debatable tbh, I generally agree that going in origin culture order is better (easier to keep consistent imo), but there are at least a lot of japanese artists that swap the name order when romanized. (And I don’t think I’d care if someone swapped my name order when speaking chinese).
Missing the “Sau” (no idea if Sau Lan is one name romanized as two words or two names) feels like a product of ignorance and pretty disrespectful though, yea.
I tend to just hop in the shower for a sec.
But all of that is only really an option at home, anywhere else it’s eternal wiping.
