Proofreading & Editing

When editing, we work to refine translated verbiage by exploiting the appropriate glossary terminology and style of the client’s preference. The ultimate objective is to make certain the content comes across as if it were originally created in the target language.

Proofreading translated content is for the purpose of ensuring a consistent and top-notch level of quality throughout the entire translated text. This is normally performed by an additional, objective native speaker of the target language .



Business meeting, site visit, marketing research, focus group, tribunal and legal proceeding, there are times that you may need a little help in communicating with a native Chinese speaker. With years of interpreting experience and deep cultural understanding, we are here to bridge that intercultural communication gap.
