Nowadays, there are differences between the new school and the old school in many dialects, which is actually due to the influence of the popularity of Putonghua on dialect vocabulary and pronunciation. The new dialect is closer to the pronunciation and vocabulary of Putonghua in all aspects. For example, many syllables of Shanghai dialect have disappeared in the new school, but they are closer to Mandarin pronunciation; The same is true of the old and new Hunan dialects.
