What is the meaning of autumn in Qing Sha Qiu Se?

Autumn is a sad and sorrowful emotional experience when people face autumn scenery. Because autumn scenery (especially in late autumn) is mostly cold, bleak and gloomy, accompanied by dusk, sunset, fallen leaves and dead branches, it becomes a symbol of the decline of all things. Therefore, on the one hand, autumn scenery can really give people a sense of physical coldness, on the other hand, it can also trigger all kinds of sadness inherent in people's hearts. Song Yu initiated China's sentimental literature with sad autumn as the main form of aesthetic experience. He expressed his frustration in life and career by describing the bleak scene of "plants dying" in autumn. He described his tragic mood in the face of autumn as like traveling, "loneliness" and "loneliness and emptiness", which shows that there are similarities in emotional experience between sad autumn and sad travel. After Song Yu, mourning for autumn gradually became one of the most common aesthetic experience forms of China literati, and it was closely linked with the sigh of life experience. Du Fu's I came from three thousand miles away. Sad this autumn "is an example. So are Ma Zhiyuan's poems. Although the image in the song is not novel and the emotion expressed is not novel, because it expresses a traditional emotional experience of China literati with refined artistic expression, it has gained immortal vitality and can arouse the admiration of later literati.
