This poem by Qiu Si Zhangji expresses the poet's thoughts and feelings.

In the prosperous Tang dynasty, quatrains were full of feelings and scenes, with less narrative elements; In the middle Tang Dynasty, narrative elements gradually increased, and daily life events often became the common theme of quatrains, and the style changed from vigorous romance to realism in the prosperous Tang Dynasty. Zhang Ji's "Qiu Si" is full of emotions. With the help of a pregnant episode in daily life-the details of thoughts and actions when sending a letter home, it truly and delicately expresses the deep nostalgia of people who are away from home for their loved ones in their hometown.

The first sentence is that the poet lives in Luoyang, and it is autumn now. The poet doesn't have a lot of thick ink to render the bleak autumn wind and the swaying vegetation. Of course, readers will not have the sadness of "autumn wind and autumn rain" in reading.

The second sentence is followed by "look at the autumn wind" and the word "think" is written on the front. Hans Zhang in the Jin Dynasty "thought of Wuzhong leek, soup, and lived because of the autumn wind, saying,' Life is expensive but you don't want it. Why do you stay thousands of miles and become famous?' Then I rode home (Biography of Hans Zhang in the Book of Jin). Zhang Jizu was born in Wujun and now lives in Luoyang. The situation is similar to that of Hans Zhang. When he was homesick, he thought about "Looking at the Autumn Wind", which may be associated with the story of Hans Zhang. However, due to various unspecified reasons, Hans Zhang could not "drive home" and had to write home to express his homesickness. This makes the homesickness already deep and strong, and adds the disappointment of wanting to return, and the thoughts become more complicated.
