No, it's true. They don't seem to have a legal middle name here, but they do all get a nickname upon birth.

It doesn't say "loe" or "Kim" or "Earn" or "nun" or "oat", or whatever on their birth certificate or driver's license, but that's how they're known by everyone. At the same time, they don't seem to ever have a middle name, like we do in the West.
