李商隐
Two poets of the generation following Li He, Du Mu and Li Shangyin, commemorated Li in their prose writings: a preface to Li's collected poems and a short biography of Li, respectively. Du Mu's preface in particular is taken as proof that Li's poetry was being compiled and edited within a few decades of his death, as internal textual evidence dates the preface to 831. The Tang author Pi Rixiu also wrote about Li He's poetry alongside that of Li Bai in his critical work "Liu Zao Qiang Bei" ().
