Wow...thanks for letting us share your amazing insights!! I too also hope the Cantonese language will continue to be prestigious, dominant and prevalent amongst the Cantonese-speaking people!!! I didn't realise that the 1,000,000,000 (that's one billion for those who can't count:-) Chinese people who do not speak Cantonese are so eager to join Cantonese language classes just so that they can understand Hong Kong pop music and films in the authentic original language. Obviously, reading sub-titles or watching dubbed films, or listening to putonghua versions of Hong Kong pop music would just be so tiresome!! Also I suppose schools all across China are introducing Cantonese language classes, and that parents are making sure their children are going to be fluent in Cantonese, just for the sake of their future of course!!
