I want to know the answer to the following question:
What type of variations are there between the Quanznou and Zhangzhou tone system?
All the background I'm provided with is that "According to the traditional Chinese system, however, there are 7 to 9 "tones",[citation needed] more correctly termed tone classes since two of them are non-phonemic "entering tones" (see the discussion on Chinese tone).". Is that enough to answer the question?
