Yes, if your goal is to make the article look more formal, it is a good idea to translate Sichuan dialect into standard Mandarin vocabulary. Standard Mandarin is more applicable in formal occasions, written documents, and national exchanges to ensure that a wider audience understands the content. If the original text contains expressions or vocabulary unique to the Sichuan dialect, converting to Mandarin will make the style of the article more standardized and suitable for formal occasions such as academic, business or official purposes. However, if some expressions in the Sichuan dialect have unique cultural connotations or expressiveness, you can also consider retaining these original expressions in the translated comments to maintain the local characteristics and original taste of the article.
