What is "dashan"

Dashan is the Chinese stage name adopted by Canadian Mark Henry Rowswell, CM (born May 23, 1965 in Ottawa, Ontario) who works as a freelance performer in the People's Republic of China. Relatively unknown in the West, Dashan is the most famous Western personality in China's media industry, where he occupies a unique position as a foreign national who has become a bona fide domestic celebrity.

Dashan is best known for his mastery of Mandarin, and most of his media work is done in Chinese. He also spoke Cantonese, the first type of Chinese he ever learnt before Mandarin, in a Ford commercial targeted at North American Chinese consumers.
