Thus Qu poems are lyrics with lines of varying longer and shorter lengths, set according to the certain and specific, fixed patterns of rhyme and tone of conventional musical pieces upon which they are based and after which these matched variations in lyrics generally take their name.The fixed-tone type of verse such as the Qu and the ci together with the shi and fu forms of poetry comprise the three main forms of Classical Chinese poetry. In Chinese literature, the Quform of poetry from the Yuan Dynasty may be called Yuanqu. Some famous Yuan Poetry Poets are Guan Hanqing, Ma Zhiyuan, Qiao Ji etc. Guan Hanqing was a notable Chinese playwright and poet in the Yuan Dynasty.
