This view is somewhat subjective, and the actual situation will vary depending on the environment and occasion. In formal business or official meetings, the use of standard languages (such as Mandarin/Mandarin) may indeed be more conducive to effective communication and professional image shaping. However, dialects also have their value and applicability.： -In local meetings, it may be more cordial and natural to use the local dialect -Within a specific industry or regional enterprise, dialect may be the norm -Many successful people retain their dialect accents but their professional abilities are still respected The key is to choose the appropriate communication method according to the occasion and to ensure that the information can be clearly understood by the target audience. Language proficiency is only part of professional literacy, and the quality of professional knowledge and expression content is often more important.
