My opinion is there is a big, big difference in the mannerisms of Northern Chinese (Beijing, Nanjing) as compared to the Southern Chinese (Guangzhou, Hong Kong). My personal experience I feel that Southern Chinese, especially Cantonese speakers, are more amicable ? They are very friendly , and quick to help out foreign tourists, and understanding. When I was in Beijing , i found the people to be colder, more to themselves , less amicable than Southern Chinese. Or maybe its just a Cantonese thing? That they are very welcoming ? My Auntie and her extended family really showed me how Chinese (Cantonese) are like. Very very family oriented...
