For Hunt, I would start with 亨 Hēng if you already use 亨特 Hēngtè. The first character is independently documented as a Chinese surname, so there is no need to discard it just because it looks unfamiliar. 韩／韓 Hán offers a useful comparison: it ends in n rather than ng and is also the first character of a documented alternative, 韓特. Choose between continuity with your existing spelling and the particular sound you prefer.
Two transcriptions worth comparing
The British government's Chinese-language announcement uses 亨特 for Jeremy Hunt. The ICRC name reference also pairs Hunt with 亨特. These show established usage, rather than a requirement that every Hunt adopt one spelling.
The National Academy for Educational Research handbook gives Hunt as 韓特. Its first character becomes 韩 in simplified Chinese. This is a real alternative to compare, not a spelling invented to justify our preferred surname.
Keep the full transcription if you want your inherited surname to remain more recognisable. Selecting one character is an additional choice for a Chinese personal name. It does not turn 特 into your given name or make the shorter form a complete translation of Hunt.
亨 keeps your written starting point
Shogakukan's dictionary places the surname sense of 亨 under hēng, the high first tone. The same entry includes an ordinary association with things going smoothly. That association may appeal to you; it does not predict success or describe everyone called 亨.
Hēng does not reproduce Hunt exactly. Collins gives the ordinary English reference pronunciation /hʌnt/. In Mandarin, the vowel changes, the nasal ending becomes ng, and the final t is lost when 特 is removed. Mandarin h also differs from the English h. Your own regional or family pronunciation remains the starting point.
The reason to favour 亨 is therefore clear and limited: it preserves the beginning of 亨特 in both character and Mandarin reading. You can introduce it as 我姓亨，亨通的亨, explaining the character through the word hēngtōng. You do not need a story about Chinese ancestry to make that explanation work.
韩 preserves a different sound feature
Shogakukan separately records 韩／韓 as Hán, with a rising second tone. Compared with Hēng, Hán retains an n ending like the one in English Hunt, but changes the vowel to a and still loses the final t. A closer match on one feature does not make the entire syllable identical.
韩 is especially worth trying if 韓特 is already your preferred transcription. If you begin from 亨特, however, switching to 韩 changes your written connection as well as the vowel, nasal and tone. Neither option should be presented as the uniquely correct Chinese equivalent.
Does the hunting meaning help?
The Dictionary of American Family Names entry describes an English occupational route associated with hunting, alongside other histories. This is useful surname background, but it does not establish your own ancestors' occupation.
If hunting or archery is a personal interest, it could inform a separate cultural naming choice, but the two activities are not identical. The 亨／韩 comparison here is grounded in published transcriptions and does not require a hunting theme.
Make the final comparison aloud
Put 亨 and 韩 before the Chinese given name you actually want to use. Say each full name, then ask a Mandarin speaker what they heard before showing the writing. Check the tone sequence, any unintended phrase and whether the family-name boundary is clear.
My starting choice remains 亨 for continuity with 亨特, and 韩 when its n ending or your existing 韓特 spelling matters more. Keep Hunt alongside the Chinese name when people need to connect it with your work or records.
Notes
Evidence for the two transcription choices: GOV.UK, 亨特, ICRC name reference, and NAER, 韓特. Surname readings are supported separately by 亨 and 韩.
Hunt is number 96 on the private British Surnames list. Its stated scope is Great Britain, excluding Northern Ireland. The reference year, counting unit and methodology are unverified; this is not an official current UK population ranking.
Sound comparisons are editorial guidance, not a recording of your family. Try the surname with your intended given name; the comparison does not establish family ancestry.
