I spent like 6 months in 雲南 and 18 in 台灣 but yeah i’m not familiar with 台山.

But for years afterwards people who i talked to would ask me about thailand, even a close friend took like 6 months to understand no, not thailand, somewhere else. I think most places you could speak cantonese and say you’re from cambodia and no one would bat an eyelid 😆
