What does Qiu Si, a poem written by Zhang Ji in Tang Dynasty, mean?

Original poem:

The annual autumn wind blows to Luoyang city, and my wandering son doesn't know how his relatives in his hometown are; Writing a letter to peace has too much to say and I don't know where to start.

When the letter is written, I am worried that I have not finished what I want to say; When the messenger started, he opened the envelope and gave it to him.

Translation:

Living in Luoyang City, autumn wind makes people homesick. I want to write a letter from home, but I have a lot of thoughts. How can I write my feelings in a hurry? The messenger was on his way when I stopped him. Open the envelope and look carefully for any omissions.

Extended data:

The first two sentences of the poem: "Luoyang City is still wanting to send a letter home in the autumn wind", and the word "autumn wind" is written, which means homesickness. The chilly autumn wind has brought coolness to Luoyang City, and it is the season for travelers to return home. Zhang, a native of the Western Jin Dynasty, missed the leeks, soup and perches in his hometown because of the sudden autumn wind, and went home with a crown. From the word "look at autumn wind", we can feel that poets are particularly sensitive to autumn wind. Connecting with Zhang's allusion, we can also touch the poet's restless homesickness.

So, following "Watching the Autumn Wind" is "I want to send a letter home". Seeing the Autumn Wind doesn't follow the example of Ying Ji's returning home to show his homesickness, so he has to express his feelings with a book, but he encounters another contradiction: "I want to send a meaningful letter from home", which is short and short, making the poet miserable. These two sentences, with only fourteen words, describe the poet's ambivalence of wanting to return and writing endlessly very delicately.
