Yanbian’s Korean Language and Writing System Regulation was revised in 2023. Article 13 treats a public sign as more than decoration: it groups plaques, notices, certificates, banners, advertisements, symbols and road signs among the texts used by government bodies, businesses, associations and individual merchants. Those texts are to appear in both Korean and China’s national common language, Chinese. Prefecture and county-level translation offices check the wording, and Korean text is to follow the standardized forms approved by the Korean-language standardization committee.
The rule connects a short street text to a chain of drafting, translation and review. In Yanji, where the prefectural publishing house is based, those same written systems continue into books and reference works. The sign is the briefest form: its words have to identify a business or direct someone along a road.
