Solar terms and rain are wet.

This sentence is a proverb in the ancient twenty-four solar terms. The ancients were very wise. They summed up many proverbs from the 24 solar terms. These proverbs are valuable experiences they have accumulated in farming. Later people can do this and usually get good results.

The rain falls on the rain festival. Rain refers to one of the 24 solar terms, which is called rain. Rainy solar terms mean that spring is coming, and the earth, flowers and trees are showing signs of recovery. Rainy festival refers to rainy days and solar terms. If it rains this rainy day, it means that the number and frequency of rain are relatively high throughout February, which is also the experience summarized by ancient farmers during farming. They must have encountered this phenomenon when they were farming in the past. There was no modern science and technology in ancient times, and their farming depended entirely on the astronomical phenomena. If it rains on rainy days, it means there is more rain in February.

If there is a lot of rain in February, it may be a good thing for agriculture. Anyway, rain is much better than drought. But it can't rain too much, and too much rain is not a good thing. Because when there is too much rain, it means that the water in the field is too high, and the seeds or other plants planted by farmers in the field cannot germinate on time, which is not a good thing for farmers. But it may be good for Shaanxi, Shanxi and the north where the land is relatively dry. Like Shaanxi, Shanxi is often dry. So if it rains, it can also nourish the land. There will be a good harvest when the crops are planted again. However, if the humidity in the south is high and it rains, the geographical water vapor will be too large, which is very unfavorable for planting.

Therefore, for ancient farmers, these proverbs are still very useful for reference. They can master the planting time and method well and avoid losing themselves.
