Came back to Hong Kong about 5 years ago. Love Hong Kong, love Canada, love to help people and see people earning a honest living. In this 知識+ Yahoo, I do not like how people copy & paste answers from textbook or the web. If I find a link for the question, I will just leave you the link, since copy & paste from a web is like plagiarism. Or at least reference it. Anyway, I will try to be as candid as possible in my answers; hope this will help the ones I answer.
