He is best known for the compilation of Chaoxian shi xuan (朝鮮詩选), a collection of several hundred poems written by Korean scholars in classical Chinese.
Heo composed a poem in Wu's honour, in which he celebrated the common brotherhood of men despite their nationalities.
On his second tour of Korea, Wu Mingqi made a concerted effort to collect the works of Korean poets.
The final work Wu produced was the Chaoxian shi xuan ("Selected poems from Joseon"), the first Chinese anthology of Korean poetry.
The Qing scholar Qian Qianyi incorporated a dozen poems from Wu's collection into his Lidai shiji (歷代詩集), as did Zhu Yizun into his Ming shi zong (明詩綜).
