Like her father, Cai Wenji was an established calligrapher of her time, and her works were often praised along with her father's.[citation needed] Her poems were noted for their sorrowful tone, which paralleled her hard life. The famous guqin piece Eighteen Songs of a Nomad Flute is traditionally attributed to her, although the authorship is a perennial issue for scholarly debate.[1] The other two poems, both named "Poem of Sorrow and Anger" (悲憤詩), were known to be written by her.[citation needed]
