Is it better to immigrate to Canada or China?

If you are from Guangdong, go to Hong Kong, because Hong Kong is a Cantonese-speaking region after all. If you are not from Guangdong, there is not much difference between going to Canada and going to Hong Kong. Let's go to Canada. But Canada is vast and sparsely populated. I'm afraid you'll feel too lonely. Hong Kong is a busy city, but it is too small. For reference only.
