Tianjingsha Qiu Si is a Sanqu by Ma Zhiyuan, a writer in Yuan Dynasty.

This song juxtaposes a variety of scenery into a picture of the sunset in the autumn suburbs, which makes the wanderer ride a thin horse on the bleak background, revealing a sad mood and expressing the sadness that a wanderer misses his hometown and is tired of wandering in autumn.

The syntax of this poem is very unique. The first three sentences are all composed of noun phrases, listing nine kinds of scenery, which are concise and meaningful.

There are only five sentences and twenty-eight characters in the whole song. The language is extremely concise but huge, with profound meaning, exquisite structure and ups and downs. It is praised as "the ancestor of Qiu Si" by later generations.
