So far I've only seen người ăn chay used to mean 'vegetarian', isn't there a separate word for 'vegan'?
thuần chay is vegan, but in my experience living here most people don't know the word.
also vegetarian is pretty close to vegan in Vietnam since there's very little dairy, and if you go to a vegetarian restaurant they usually don't use eggs
So far Duo has always translated người ăn chay as "vegetarian". Suddenly in this it must be translated "vegan" or the sentence is marked incorrect. Are you joking?
