It's not a transliteration. What supposed writing system are Vietnamese originally writing in, before they transfer it to Latin script?

Chinese-like characters, which were transliterated by Europeans into Latin. This system was made official by the French rulers of Vietnam.

So you're saying that because the country was once colonized, their writing system is not "real" enough for you, and you only consider it a transliteration? That seems extremely disrespectful.
