Cantonese words "kam pou" were derived from the word Kampar, rather than the other way around. Curiously, Kampar Regency in Sumatra was where the 1st Sultan of Perak (Sultan Mudzaffar Shah) was based before becoming Sultan of Perak in Perak (his highness was a son of the last Sultan of Malacca).
The local Chinese community had the impression it came from the Cantonese word kam pou as it means "precious gold" (referring to the town's previously large tin reserves). This is misleading as they were not aware of the history of the area and its historic relation to Kampar (Riau) as stated in the paragraph above
