I am asian and I was raised in a cantonese-speaking household, but did not live in an asian country. My cantonese was learned by listening to my parents. I can speak cantonese but my vocabulary is very limited.
I want to learn to improve my cantonese to a wider vocabulary and I want to learn mandarin as well in case I visit an asian country, or meet one of my dad’s friends I don’t want to not know what to say.
How long would it take to learn?
