What are the functions of "xiao" and "xin" in the poem A Sunny Sun and Dawn Light?

This poem is taken from Fan Chengda's "The Wind Stops": "

After all the storms and rolling away the clouds, a clear pole with a clear sun and a new dawn.",," The word "Xiao" means that after the storm, the morning sunshine sweeps away yesterday's haze. "Xin" means "dawn" and governs the first fourteen characters of this poem. It becomes a trend of suppressing first and then rising, writing the spirit of freshness and splendor in spring and the recovery of all things.

Although the words and sentences describe the scenery, it is not difficult to see that they contain the poet's love for spring. It expresses the poet's sincere joy.
