I asked a similar question in a different thread and received different responses. But the problem was most of these posters didn't speak canto. I understand why considering its literally probably one of the hardest languages to learn if English is your native language, also considering most of their co workers can speak English. But I didn't know if I should take their advice since they wouldn't know how their life would be if they knew canto. That's why i'm looking for expats who learned canto, few questions.
-How long did it take to get around conversational fluency?
-Was it worth the time and effort?
-How was the improvement on your social life?
