They're all Anglicized, i.e., written in English consonant-vowel
patterns. So, they're all easy to pronounce.
1. shatin - unfortunately, this rhymes with a swear word for the act of
defecation i.e., "shitting" - sometimes the ending 'g' is dropped in
English so the pronunciation rhymes even more "shittin'" - "shit" is a
swear word for feces - "shat" is the past tense of "shitting" -
due to various accents, southerners in the U.S. could pronounce
"shitting" as "shattin'" - accents in the U.S. are from other
non-English European languages such as French, German, Italian, Spanish
mixed with English - I would not suggest using "shatin" due to rhyming
and/or differences in regional pronunciations in the U.S.
2. kowloon - U.S. people know this word - e.g., walled city, slum -
also, it's a common name for Asian cuisine restaurants in U.S.
3. fanling - this has the word "fan" in it which means a) machine with
blades that blows air and b) people who really like something, such as a
music group or sports - the ending -ing is common in English - "ling"
doesn't refer to anything in English - this seems to me to be the most
neutral word of the four, as U.S. English speakers are unfamiliar with
it, it has one good word in it, it has a common English ending, ...
4. taiwai - U.S. people are familiar with Taiwan and support it - the
Chinese government may not wish for U.S. people to associate a product
named taiwai with Taiwan
Countries that won't talk to Biden: North Korea, China, Russia, Iran.
