Including autumn, through the introduction of autumn scenery, the whole poem is more sentimental and sad. Autumn is a sad and sentimental season in the works of literati in past dynasties, but it lacks the cold of winter, which echoes the warmer weather in the local Yangtze River basin. In addition, in order to show the seasonal changes more vividly, non-seasonal scenery and scenes are described and used as the heroine's activity scenes.
