Therefore, it may be close to the fact that it is the central dialect that combines the remaining dialects except for other dialects where distinct characteristics are observed, rather than having a specific phenomenon observed only in the central dialect. Since the central dialect consists of sub-dialects that are more heterogeneous than other dialects, it is more likely to be divided into several sub-dialects than any other dialect.
