Good rain knows the season, when spring comes.
Sneak into the night with the wind, moisten things silently.
The wild path is dark, and the river is bright.
Look at the red and wet place, the flowers in Jinguancheng are heavy.
Praise "rain" with a word "good" at the beginning of "good rain knows the season and spring comes" in life. "Good" is often used to praise people who do good deeds. Praising rain with "good" now will arouse the association of people who do good things. Next, personify the rain, saying that it "knows the season" and knows how to meet the objective needs. Among them, the word "knowledge" is used incisively and vividly, which simply brings the rain to life. Spring is the season when everything germinates and grows. As long as it rains, it begins to rain. It's really good.
Zhuan Xu described the occurrence of rain by "sneaking into the night with the wind, moistening things silently", which further showed the beauty of rain, and the words "diving", "moistening" and "fine" vividly described the characteristics of rain. Rain is "good" because it is good at timing and "moistening things quietly". Spring rain usually moistens everything with breeze and drizzle. However, there are exceptions. Sometimes, it will be accompanied by cold air, from rain to snow. Sometimes, it will be accompanied by strong winds and heavy rains. Although the rain at this time is in spring, it is not a typical spring rain. It will only hurt things, and it will not "moisten things quietly." Naturally, it will not make people "happy" and it is impossible to get a "good" evaluation. Therefore, the "knowing season" of the first couplet alone is not enough to fully show the "good" of rain. It was not until the second couplet wrote a typical spring rain-accompanied by gentle rain-that the word "good" was implemented. "Sneak into the night with the wind and moisten things silently." This is still anthropomorphic. The combination of "sneaking into the night" and "silence" not only shows that rain is drizzle accompanied by breeze, but also shows that rain is intended to "moisten things quietly" and has no intention of seeking "goodness" If you are interested in seeking "good", it will come during the day and create a little momentum for people to see and hear clearly. Just because it deliberately "moistens things quietly" and has no intention of seeking "goodness", it chose a time that does not hinder people's work and labor, and quietly and carefully went underground at the night when people were sleeping.
