This is enough to discredit the whole infographic in my eyes. No matter what the CPC or anybody else may claim, these are distinct languages, and not dialects. Not only that, but in some of these places a lot of Chinese speak other regional Chinese languages, such as Fuzhounese, rather than Mandarin or Cantonese. (I remember a blog from twenty or so years ago by a NYC Chinatown native who mapped his building by language; something like a dozen Chinese languages were spoken by residents of that building's apartments.)
