Language is the carrier of culture, and the change of language reflects the change of culture. The Book of Changes, as an ancient philosophical system, mainly focuses on the changing laws of everything in the universe. As a regional linguistic phenomenon, Gangu dialect mainly reflects the phonetic, lexical and grammatical features of this region. Some characteristics of Gangu dialect can be regarded as a form of expression under the local cultural background, which is consistent with some ideas in the Book of Changes.
