Philosophy and literature grew to new heights in the Qing period. Poetry continued as a mark of the cultivated gentleman, but women wrote in larger and larger numbers and poets came from all walks of life. The poetry of the Qing dynasty is a lively field of research, being studied (along with the poetry of the Ming dynasty) for its association with Chinese opera, developmental trends of Classical Chinese poetry, the transition to a greater role for vernacular language, and for poetry by women. The Qing dynasty was a period of literary editing and criticism, and many of the modern popular versions of Classical Chinese poems were transmitted through Qing dynasty anthologies, such as the Quan Tangshi and the "Three Hundred Tang Poems". Although fiction did not have the prestige of poetry, novels flourished. Pu Songling brought the short story to a new level in his "Strange Stories from a Chinese Studio", published in the mid-18th century, and Shen Fu demonstrated the charm of the informal memoir in "Six Chapters of a Floating Life", written in the early 19th century but published only in 1877. The art of the novel reached a pinnacle in Cao Xueqin's "Dream of the Red Chamber", but its combination of social commentary and psychological insight were echoed in highly skilled novels such as Wu Jingzi's "Rulin waishi" (1750) and Li Ruzhen's "Flowers in the Mirror" (1827).
