The first sentence points out the light rain in early spring, and describes it as smooth and moist with "moist as crisp", which accurately captures its characteristics. The sentence is fresh and beautiful. There is also Du Fu's "Good rain knows the season, when spring comes." Sneaking into the night with the wind, moistening things silently "has the same effect."
The second sentence closely follows the first sentence, which describes the scenery after the rain. From a distance, it seems to be there, but from a close look, it depicts the hazy scene of grass soaking in rain in early spring. Write down the characteristics of spring grass when it just germinates, if not, sparse and short. This sentence is a wonderful sentence in the whole article.
