One reason that European culture is so vibrant is that many local languages are well preserved and continue to thrive. Some small European countries actually have more official languages than the larger ones.
Switzerland, for example, has four, despite a population that is one-third the size of Taiwan’s. The land is divided into German, French, Italian and Romansh zones, in which the central government respects all languages equally without discrimination.
If one writes to the central government in one of these languages, a reply would come in the same language. However, in-person services are delivered within a region’s dominant language.
