Recently there is a hot debate on a report that some employees of a metropolis subway company start using dialects to cater to the requirements of people from different areas in order to render better service lately，Opponents sees the countering effects of such movement to the national policy of promoting mandarin across China。Benevolent see benevolence, the wise see wisdom. In my opinion, I believe dialects are acceptable in public places Firstly, in a sense, thedialect is the matrix of Mandarin, dialect can retain many many syllables and meaning that have disappeared, and can enrich the expression, the popularity of Mandarin is actually a kind of cultural assimilation phenomenon ,while the existence of dialects can keep The richness and variety of the language, moreover dialect is a tradition of culture and a tie, as we know, the great and the profound Chinese culture is reflected in all levels, the diversity of local dialect is part of traditional culture Secondly, from the cultural perspective, globalization and localization are not contradictory. Mandarin and local dialect has not contravene each other, Mandarin has changed from a great deal of language , but also learned the local dialects of certain languages, so the two are blending. There were popular cartoons with dialect version at one time, such as "Tom and Jerry" , which had Sichuan dialect version, northeast dialect version , dialect Tianjin version, Henan dialect version and other versions. This was typical phenomenon that globalization and localization were joined together , "Tom and Jerry" is a symbol of globalization, and dialect voice indicates the reaction of localization. Audiences all over were delighted to hear and see this dialect version of the cartoon, unfortunately, it was called vulgar once and became the object of regulation. Perhaps there will be some indecent words in dialect, but this is not the special property of dialects, because mandarin has the same lack of such words,it’s impossible to limit on the use of mandarin for those reasons. Moreover, in order to communicate with each other widely, Putonghua should be popularized fully in public. However, in public culture, dialect has become strike-hard objects, which will not only cause harm to the dialect , but also do harm to the public administration, public services and public culture. An international metropolis needs to think mandarin as the main communicational language in public administration and public services, at the same time we should keep the appropriate space to dialect 本文来源：https://www.wddqw.com/doc/d242ffc12cc58bd63186bd35.html
