Quick Answer: What Is the Wei Surname Written 卫?
This Wei surname (卫/衛, wèi) is a Chinese family name pronounced with Mandarin’s fourth, falling tone. Its character also means to guard or protect.[1]
- Characters: 卫 is simplified and 衛 traditional; the variant form (衞, wèi) also occurs in records.[2][3]
- Traditional connection: An old surname account links the name with the ancient Wey state (卫国/衛國, wèi guó).[4]
- Recorded forms: Wei and Wai appear in identifiable records of this surname.[5][6]
Other surnames also become Wei in Roman letters, so the Chinese character matters.

A surname index may use 衛 where an older book prints 衞. Meanwhile, a person’s English name may use Wai. Recognizing those forms helps with searching, while preserving the spelling actually found in each document.
卫, 衛 and 衞: Characters and Meaning
The simplified–traditional pair is 卫 and 衛. The form 衞 is a recorded variant of 衛, not the simplified character.[2][3] Keep the actual form when transcribing a name; put a normalized search form in a separate field.
The word’s meanings include guarding and protection. Its use as a surname does not imply that every bearer’s ancestors worked as guards, or that a person has a particular protective temperament.[1]

The Wey State in the Traditional Surname Account
Tongzhi (通志, tōngzhì) connects the surname with the state associated with Kang Shu (康叔, kāng shū), describing descendants adopting the state’s name. Here, Wey distinguishes it from another ancient state written Wei in English.[4]
The account describes changing centres: Chaoge (朝歌, cháogē), then Chuqiu (楚丘, chǔqiū) and Diqiu (帝丘, dìqiū). Thus even the traditional state narrative involves several places, not one unchanging family village.[4]
This explains an established account of the surname’s formation. It does not document the intervening generations between an ancient state and a modern family.
Wei and Wai in Actual Records
- Wei: The author authority record for Wei Juxian (卫聚贤/衛聚賢, wèi jùxián) gives the Roman index form “wei, ju xian” and lists 衛, 衞 and 卫 forms of his surname.[5]
- Wai: A university medical-system profile records Abraham Ka Chung Wai (卫家聪/衛家聰, wèi jiācōng), supplying an actual Wai name rather than a spelling rule for every family.[6]
The catalogue links several written forms to one identified author. Similar-looking names in unrelated records still need confirmation.
