After you learn the words Thank you in Shanghainese, you will probably hear this phrase. In English the best we can do is “NOT AT ALL” or “DON’T worry about it.” But in Mandarin it is much easier and faster. But in Shanghainese it is ten times more fun to say. MX’s mother (my mother in law) would say it in funniest way. Some people on the street would say it in a fast and slurred way. Anyway you say it, it makes you sound more like a Shanghai person! SO SAY IT!
