What does the poem "When the Dawn Comes and the Sunset Sunsets" mean?

The definition of "the dawn is light and the sun is shining" is that it begins to rain in Mao Mao at dawn, and it is spent in the dark during the day and in the evening.

The sky will clear up in a few minutes.

This poem comes from the Tang Dynasty, "I didn't have time to fill the post with water, but sent it to China to make Zhang Zhenger serve the court". The original text is as follows:

The spring rain is like smoke, and when dawn comes, it will faint at sunset.

Cactus on the lotus swamp, pillar history Kansai pine and cypress temple.

How old is China when he sells roads? King Wuji is a military division.

Looking back on the two wonders, there are three peaks in the day.

Dou Mou, the word Yizhou, is from Ping Ling. Zhenyuan is a scholar and a left-behind judge. Shangshu is an official card shark, Zezhou is a secretariat, and ultimately a national son. The original set has been separated. There are ten volumes and twenty-one poems today.
