In some formal settings or international conferences, a standard or common language is often used for communication, with the goal of ensuring that all participants can understand and communicate. Therefore, speakers of dialects may face communication challenges in certain situations, which in turn affects the extent to which their opinions are heard and valued. However, this does not mean that dialects themselves are not valued. Dialects are an important part of cultural and regional identity and can reflect rich cultural diversity. In certain conferences or forums, especially when themes such as culture, local affairs or linguistics are involved, the use of dialects may be more resonant and reflect cultural background. The degree of value usually depends on the speaker's expressive ability, language suitability and the audience's understanding background. To ensure that they are valued in a multilingual environment, speakers may need to use the appropriate language in the appropriate situation, accompanied by clear expression and strong arguments.
