Who knows that sad poem in late autumn?

I haven't read this poem, but try to understand it.

Is the topic "Don't leave sadness in autumn"? But the emotions and images expressed in the whole poem are lonely, barren and sad, so I think the meaning of the title is: What a woman said to her lover who left her: Don't leave me in the already sad autumn, and don't leave your sadness in the autumn!

The first paragraph: slender hands are gently raised to bid farewell to you, and long hair hangs down (the old friend has gone, and the long hair hangs down). Although the field paths in early autumn are still criss-crossing, summer is no longer green, so it is so deserted. I walked through an antique alley with a floral umbrella. In this boundless autumn rain, lonely "I" looked at the falling red leaves, in order to see you.

The second paragraph: once the courtyard was full of spring, once the lush trees, but now it is so thin How do geese flying south describe the traces of time passing? On that day, in the sky with high clouds and light wind, the geese went back to spring in autumn, but refused to tell the legend, right?

The third paragraph: the long wind of autumn night blows through the quiet night. Who decided to leave, broke my heart and broke the empty moon shadow in the pool? When the waves stop rippling, the shadow of the moon is also disillusioned. Your wandering flute took my heart and sobbed all autumn. You took away my heart and the sadness you brought.

Pure personal understanding, please forgive me for my shortcomings. If you are considerate, give me more. I'm exhausted. . .
