Different from those fixed and tangible material cultures, intangible culture is a cultural heritage that has been passed down from generation to generation, passed down from mouth to mouth and practiced artificially. At the same time, intangible culture has the characteristics of naturalness, persistence and inheritance. The preservation and inheritance of intangible culture need to establish a model in many ways, a method that can make intangible culture inherit well.
In the whole process of oral English teaching, language communication is involved, and before there is a unified language, local areas in every place communicate with dialects, so many intangible cultures use dialects as a medium to teach communication.
With the progress of the times and the tide of economic and social globalization, many traditional folk cultures are facing severe challenges. Many distinctive folk arts have been lost or disappearing, and many unique folk stunts are also facing the state of no successor. Many intangible cultures created by the older generation urgently need people to inherit, while many people of the older generation use the original dialect to communicate, which can also be said that dialects have become an important tool for intangible cultural inheritance.
When realizing the problem of intangible culture inheritance, many TV media, documentaries, movies and other online media are also recording and protecting intangible culture. From language to TV media, this is a progress, with more effective ways to protect intangible culture, but it is also difficult to bury the role played by dialects in the inheritance of intangible culture for so many years.
