How did the autumn rain of Tang Dynasty poet Li He come from?

Quotations from Li Ping. Nu Wa makes up the sky by refining stones, and the stones break the ground to stir up the autumn rain. These two poems are from Yu Liping Yin written by Li He, a poet in the Tang Dynasty. The original text reads: "Twelve gates melt cold light, and the twenty-third line moves the purple emperor. Nu Wa tempered the stone to make up the sky, and the stone broke the ground to stir up the autumn rain. " The meaning of these two poems is: high-pitched music goes straight into the sky and rushes to the sky where Nu Wa fills the stone. It seems that the colorful stone that filled the sky was broken, and the autumn rain fell all over the sky.
