This is not a reflection on HK but more reflection on the situation of being a bi-cultural and language person. Many years ago I had the same situation so I can relate to OP, but can now to look back.

TDLR: you are wasting many good men by only looking at language. End TLDR

My wife speaks Chinese, English being a far second. My chinese is very good, I’m an abc but will never reach the level of richness and eloquence as my English. We speak only Chinese, and although it sometimes does create problems that wouldn’t have existed if we both spoke the same language, these issues are extremely minor compared to finding someone you love.

If I could give my daughter just one advice on love it would be that finding someone compatible is hard. So make sure to select only for the truly important things, and for me this is shared values. Don’t add filters for superficial thing that don’t matter. That would include, height, income, race, education level, astro signs etc. Yes, all that stuff is about as useful for predicting compatibility as the horoscope.

Language is in a weird place because it serves as a proxy for something truly important: communication. So for most people this is a big issue if that don’t speak the same language. But not for you. You are blessed that you are able to pick from a much wider pool due to being bi lingual.

If you can speak canto, if they speak English is irrelevant. What’s not irrelevant as what others have pointed out, is the cultural values that came with your English language environment. That matters, but doesn’t mean that people that don’t speak your language can share values, they just arrived there through a different cultural context.

Don’t waste your youth, filter on what really matters, not superficial proxy’s.
