In 1923, the Preparatory Conference for the Unification of Mandarin decided to adopt the Beijing phonetic standard to promote language and dialect throughout the country, not as a tool of communication, but as a cultural carrier.At present, the miniaturization of dialects, even if the culture of one side fades, maintaining the coexistence of dialect national language and common language is conducive to maintaining cultural diversity. While popularizing Putonghua, dialects should also be given some room for expression.And the dialect is not large, applied to one side of the land, but also can enrich the color of the common language, such as happy to pay for the high and unfinished buildings and other words have entered the common language vocabulary, and have some development.
Common language identification is conducive to improving the cultural level and scientific and technological development level of the whole nation is the gist of the above.
