His name is permanently associated with the “Chēgài tíng shī àn” 車蓋亭詩案 (Carriage-Canopy-Pavilion Poetry Case) of Yuányòu 1 (1086): exploiting personal animus against his political rival Cài Què 蔡確, Wú denounced Cài’s set of Chēgài tíng shī poems as allegorical slander of Empress Dowager Gāo 高太后, then in regency. The Yuányòu government, with Sīmǎ Guāng as chief minister, accepted the denunciation; Cài Què was demoted to Yīngzhōu and died there; Wú was rapidly promoted. The precedent for political construal of poetry was a shaping event of late-Northern-Sòng literary culture. His one surviving work is the KR3l0035 Qīngxiāng zájì 青箱雜記 in 10 juàn, composed probably in his post-promotion years (c. 1080s), containing court anecdote and substantial poetry-talk material.
