What does it mean to believe Jiaojiang dialect?

Believing in Austria means not believing.

The reasons for the formation of dialects are complicated. For example, the influence of aboriginal language, the change of itself caused by the passage of time and the barrier of geographical environment, etc. But the most important factor is the language differentiation and aggregation caused by immigration in history.

For example, the Qin Dynasty invaded Baiyue in the south, and a large number of soldiers and officials immigrated to Guangdong and Guangxi, which contributed to the formation of Cantonese. For another example, the migration of nomadic people in the north led to the phonetic changes of northern mandarin. So there are historical reasons behind the formation of each dialect.
