Henan Anyang dialect and Linzhou dialect are so different that they didn't belong to the same country before? The problem of administrative division? Seek a detailed explanation

I have done a special study on Linzhou dialect, and compared the accents of people in some counties and cities around Linzhou through audio, trying to draw scientific conclusions through speech recognition.

In fact, I found out later, what's more, the pronunciation of Linzhou and Anyang is very different. Only the Shijiagou accent next to Donggong Road is obviously different. It can be seen that accent dialects are not directly related to whether they belong to the division of state-level administrative regions.
