Transliteration is not translation
A surname is a proper name. Translating its dictionary meaning into Chinese is usually a mistake. Transliteration represents the sound with Chinese characters, while a shortened existing Chinese surname is sometimes chosen as a practical adaptation.
Conventions can vary
For example, Smith may appear in a full phonetic transliteration or be shortened to an existing Chinese surname such as 史, depending on the person, context and preference. Neither approach is universally correct. The important question is which form will be used consistently across documents, accounts and introductions.
Compound and unusual surnames
Long or less common surnames may use several characters. Do not split them arbitrarily into a Chinese given name. Check the complete transliteration and confirm where the surname ends and the given name begins.
Forms and records
On official forms, put the legal surname in the family-name field and the given name in the given-name field. Do not reorder the name just because the Latin-script version looks more natural. Consistency prevents problems with passports, visas, bank records and academic documents.
What to verify
Ask a native reader to say the transliteration aloud, check for awkward homophones and confirm that the chosen characters are appropriate for a name rather than a random sound match.
