What is the theme of Tianjin Sha Qiu Si?

This Sanqu is Xiaoling's.

Tianjingsha Qiu Si is a famous Sanqu written by Ma Zhiyuan, a poet in Yuan Dynasty. By depicting the natural scenery, the work renders a bleak and miserable artistic conception and expresses the poet's yearning for his relatives in his hometown. Xiao Ling is a form of Yuan Qu, and each Xiao Ling usually consists of five sentences, which are short and pithy, expressing emotions directly and richly.

Ma Zhiyuan's "Tianjingsha Qiu Si" was praised as a masterpiece in Yuan Dynasty for its profound thoughts and feelings. It vividly depicts the autumn scene with refined brushstrokes and expresses the homesickness of the wanderer.
