How to explain this rain?

There are several explanations for the rain:

1, "Falling in the rain, falling in the rain, falling in the sky." In other words, it rains in dog days, and it often rains in dog days. Seeing the rain means that there will often be rain in the rainy days in the future, which is a good year for good weather. If the rainy day is sunny, it indicates that there will be little rain for a long time in the future, and it may dry to the horizon. "Horizon" means the edge from summer to autumn.

2. "There is rain on your head and rain on your knees." This means that if it rains when it is falling, it means that there is more rain when it is falling, and the temperature is not as sultry as in previous years.

3, head leakage, dried bean leakage. The word "leakage" stands for rain. The whole sentence means that if it rains on the falling day, there will be less rain in the following weather, and the crops in the field will encounter drought, and the planted crops may die because of drought.
