Info on Cantonese people ! Source http://www.cantonese.ca/intro.php Cantonese (or Yue) is one of the five major Chinese languages. These are often called "dialects", but in actuality their differences are great enough to consider them separate languages. Cantonese is spoken by about 100 million people in the southern provinces of Guangdong and Guangxi and in neighboring areas such as Hong Kong and Macao, as well as throughout South-East Asia in such places as Singapore, Malaysia, Thailand and Vietnam. Due to the migration of Cantonese speakers from Hong Kong and the Guangdong area, Cantonese is the dominant form of Chinese spoken in the Chinatowns of many major cities in the United States, Canada, Australia and elsewhere.
