My wife is Korean. The anglicized version of Korean given names always has a space in it. This makes for a few kinds of broken naming schemes - like removing the space or the second half of the given name becomes the middle name, or the second half of the given name just truncated entirely.

In Singapore given names can have more than one space and may not be a substring of the full name. The first prime minister has the full name "Harry Lee Kuan Yew" where Lee is his family name and "Harry Kuan Yew" is his given name. (Later in life he dropped "Harry" from his name.)

To be more precise, many Singaporean Chinese names are formatted as WESTERN_NAME SURNAME CHINESE_FIRSTNAME_1 CHINESE_FIRSTNAME_PART2. The WESTERN_NAME may or may not be a legal name (AFAIK for Lee Kuan Yew it never was), and to further complicate things it's not unknown for the Chinese name to be duplicated in its dialect and Mandarin readings, leading to "Harry, Lee Kuan Yew (Li Guangyao)".

Combine this with Anglocentric IT systems, and I'm sure Mr Lee (RIP) gets a lot of spam addressed to "Mr Yew".

I get this in reverse. My surname is Parks, and my given names are Paul Moore. Since moving to Singapore I've become accustomed to answering to "Parks Paul Moore" in person or on the phone.

Surprisingly, local systems outside of the SG government can still take a maddeningly Western approach to names (First name/last name, assumption that last name is a family name a not a patronymic, etc.). My wife is Singaporean Tamil, so her "last name" is actually her father's given name, and even when travelling around Southeast Asia she encounters issues with this.

Fortunately, the SG government does an admirable job of handling Chinese names (across a number of languages and cultures), Malay names, Indian names of various cultures (mostly Tamil, but also Punjabi, Malayalam, and several others) and of course many Western names. I wish the Western world would catch up.
