Contrary to what you might think WPE, Indians do live in other parts of Hong Kong. I suggest you crawl out of your shell and see for yourself.
The idea here is to offer advice, as I have done in my previous post, as opposed to your idea of help - indulging in a negative stereotype!
Your comments are not only inappropriate, they are highly offensive (and racist!)
I suggest that you reflect on what I have just said, and instead, YOU go and watch a movie, or read up on books about etiquette. Trust me, you need it!
