You know Taiwan is Chn next conquering target! SO for little red to call themselves taiwanese is like being enemy of motherland.
To little red book, SG is like an upgrade on "reputation"! For example Its like you ask another sinkie where he stay, if he says Yishun! People reaction will be 😱.. So Sinkie will say they stay in bukit timah road or Holland V! 😎 Right!!!!
So those little red book also know how to fake it till if they make it! They behave badly. its SG problem!
