Translation studies has gradually established itself as an independent field of study over the past three decades or so, and in this relatively short period of time we have witnessed an overwhelming increase in publications on translation. Besides, the voice of a good translation is as distinctive in English as the author’s voice in the original language, also when compared to other authors translated by the same translator. A good translation accepts the gifts English offers and is not an endless procession of compromise and loss. A good translation is something to aspire to and, in this perfectionist’s profession, a good translation is never good enough.

As a result, I thoroughly understand the people, culture, critical thinking and social fundamentals in both English and Vietnam.
