Lài Wénjùn 賴文俊
Style name Tàisù 太素; sobriquet Bùyīzǐ 布衣子 (“Master of Cloth-Robes” — i.e., self-styled non-official); commonly known as Lài Bùyī 賴布衣 (Lài of the Cloth-Robes). Native of Chǔzhōu 處州 (in modern Zhèjiāng). Active in the Sòng (probably the Southern Sòng); birth and death years not securely recorded.
A Sòng-period geomantic specialist who served briefly in office at Jiànyáng 建陽 (Fújiàn) before abandoning his post and devoting himself to geomantic practice and travel. The 提要 of KR3g0026 Cuīguān piān records his nickname Lài Bùyī as the conventional reference. Other works attributed to him: Shàoxìng dàdì bāqián 紹興大地八鈐 and Sānshíliù qián 三十六鈐 (both lost). The Sìkù preserves only the Cuīguān piān.
Lài Wénjùn became one of the most popularly-celebrated geomantic figures of late-imperial Chinese folk culture, with extensive legendary elaboration in southern-Chinese (especially Cantonese-and-Hakka) folk tradition. His works represent a sophisticated xíngshì (form-and-configuration) school methodology with distinctive contributions to the yīnyáng wǔxíng (yīnyáng five-phase) generation-and-restraint analysis of geomantic configurations.
