Why are there so many Russian signs on a road in Sanya, Hainan?

Add public service announcements and bilingual advertising signs. The proportion of public service advertisements and multilingual advertising signs directly reflects the civilization and openness of a city. As an international coastal tourist city, Sanya should have higher requirements in this regard. Therefore, it is necessary to increase public service advertisements in our city and increase advertising signboards in English, Japanese, Korean, and Russian, especially bilingual or even multilingual advertising signs in scenic spots, hotels, shopping malls, and main streets. Foreign language advertising signs should be translated or reviewed by professionals to avoid errors.
