The Hokien language (spoken widely from Thailand, through Indonesia and Malaysia, as well as in Hokien and Taiwan) has "regional dialects" that use ALL 8 old form tones! Of course they also have a vocabulary that is about 30% Dutch in origin. Makes for some interesting listening!
There is no "Chinese". There are dialects- Mandarin, Cantonese, etc. Mandarin - the official language of China - has 4 tones.
