Wen is the pinyin romanisation of the Chinese surname 文 (Wén).
文 (Wén), meaning "literary" or "culture", is usually romanised as Man in Cantonese (most widely used by those from Hong Kong), and sometimes as Mann.
In Min (including the Hokkien, Teochew, and Taiwanese dialects), the name is pronounced Boon.
The Gan dialect transcription for the name is Mun.
Other romanizations include Văn in Vietnamese, Moon or Mun (Hangul: 문) in Korean and Bun (Hiragana: ぶん) in Japanese.
