Simplified Chinese vs. Traditional Chinese: Choosing the Right Script
Choosing the right script is one of the most important parts of any English to Chinese translation project. Simplified Chinese and Traditional Chinese are not interchangeable, and using the wrong version can make your content feel out of place from the start.
If you need professional Chinese translation for official documents, business materials, or certified translations, your content needs to match the market, the reader, and the expected written standard.
Simplified Chinese, or 简体中文, is widely used in Mainland China, Singapore, and much of Malaysia’s Chinese-language written communication. Traditional Chinese, or 繁體中文, is commonly used in Taiwan, Hong Kong, and Macau. That is why professional translators look beyond the language pair alone. A well-prepared translation also takes into account locale codes such as zh-CN, zh-SG, zh-TW, and zh-HK, along with regional wording, date formats, names, and usage preferences.

What "Certified" Really Means for Chinese Translation
Certified Chinese translation is typically required when a document will be submitted in an official setting and must include a signed statement confirming the translation is complete and accurate.
Accepted by Courts and Chinese Authorities
Certified Chinese translation is often required for documents submitted in official settings. That can include academic credential evaluations through organizations such as WES, ECE, and materials prepared for use in US federal and state courts. It may also apply to documents prepared for review by Chinese authorities or other regulated bodies, depending on the filing purpose.
Certifications
Certified Chinese translation often includes a signed Certificate of Translation Accuracy for documents prepared for formal submission. This certificate states that the translation is complete and accurate to the best of the translator’s knowledge. It also helps the receiving office verify the language pair, translation provider, and contact details tied to the completed file.
