Similar stuff is happening in multi-ethnic Singapore too. Descendants of earlier ethnic Chinese migrants living in South-East Asia have developed their own ethos/culture, with huge influences from the other ethnic groups. With a flood of China Chinese immigrants arriving on Singapore shores in recent years, various conflicts arise. E.g. The "No cooking or eating curry" uproar resulting in the "Cook and share a pot of curry" backlash event.
I wonder if something similar would happen in Richmond (dubbed the Chinese enclave) or other parts of Metro Vancouver. In Canada, earlier waves of Chinese immigrants were mostly Cantonese-speaking from Tai Shan ［台山］ or Hong Kong or other parts of Southern China. I wonder if they would have open conflict with the newer Mandarin-speaking Chinese immigrants from China. Personally, I have observed subtle prejudices from both sides to the other party. Being both Mandarin and Cantonese speaking (albeit not excellent in either), I am perched on an interesting no-man's land whereby I get to hear "stories" from both parties.
Yes, I was ever laughed at by Hong Kongers for my broken Cantonese. Yes, I was also ever laughed at by China Chinese for my half-past-six Mandarin. But guess what? In Metro Vancouver, being able to speak both gives me an upper hand for either side to consider me "自己人" [a member of their in-group].p.s. If you can read Cantonese (or use a translator), you can see the Facebook url below for the Hong Konger's side of the story. 對於《香港人大戰內地人》by Ken Wai on Monday, 16 January 2012 at 21:27.
