Ma Zhiyuan's Autumn Thoughts on the Clear Sky Sand

Ma Zhiyuan (1250 - 1321), also known as Qianli, also known as Dongli, was a native of Dadu (present-day Beijing) and Dongguang County, Hebei Province. Together with Guan Hanqing, Zheng Guangzu, and Bai Pu, he was known as the "Four Great Dramatists of the Yuan Dynasty". He was a famous dramatist and Sanqu composer of the Yuan Dynasty. This song depicted a picture of the autumn countryside at sunset: "Withered vines, old trees, crows, small bridges, flowing water, and thin horses on ancient roads in the west wind. The sun sets in the west, and the heartbroken man is at the end of the world." The first four sentences were all about the scenery. Words such as "withered","old","faint", and "thin" made the rich autumn colors contain an infinitely desolate and sad mood. The combination of various scenes formed a picture of a wanderer riding a thin horse in the desolate background. It revealed a sad mood and expressed the sorrow of a wanderer who missed his hometown in autumn and was tired of wandering. Ma Zhiyuan was passionate about fame when he was young, but because of the high pressure policy of the rulers of the Yuan Dynasty, he had never been able to achieve his goal. He had been wandering for almost his whole life, depressed and destitute. He wrote this song while he was traveling.
