1. See what whitehead cream is?
Whitehead Cream : Just like an old man with silver threads on his head, here, it means that the top of the grass is covered with frost flowers , silver-white.
This is a natural phenomenon. When the outdoor temperature reaches below zero, the water molecules in the air will condense into frost, which we commonly call frost. The basic condition is below 0℃. In the early morning, a layer of frost will form on the surface of grasses, trees, ground and other objects.
From the twenty-four solar terms, it is usually necessary to reach Frost Descent solar terms, which is around October 23, the time is around October 23 of the Gregorian calendar. At this time, the temperature reaches freezing point, the temperature drops in the morning and evening, and the frost Descent begins to appear.
2. How to understand: "After the whitehead frost, the mosquitoes rest on the top of the tree."
From the proverb, the meaning is easier to understand, that is, when frost occurs or the Frost Descendant solar term occurs, at this time, the mosquitoes basically disappear, some are frozen, and some are hiding among the trees, preparing to spend the winter and welcome the arrival of spring.
This is more in line with the living habits of mosquitoes. We know that the growth period of mosquitoes usually starts to appear in March and April of each year, flying everywhere; the activity is the craziest at around 25℃, and when it reaches around 10℃, the activity slows down and some are hidden.
Wait until now, when it reaches below 0℃, which is the season of frost, the mosquitoes have also hidden themselves and hide in dark and warm places such as trees, preparing to spend the winter. Around November, which is the season of frost, it is difficult to see annoying mosquitoes again.
3, "I drank white dew, the mosquito shut up his mouth", does it make sense?
It seems that mosquitoes are basically unable to survive when they are in the frost season, and they are below zero degrees.
Some agricultural proverbs say: "In autumn, mosquitoes are as fierce as tigers, and after autumn, mosquitoes bite people to death." . This is for the time when the weather is just hot and cold after autumn, it is very suitable. Mosquitoes start to bite people or livestock everywhere, storing energy, and preparing for winter. Therefore, it is about 25℃, which is when mosquitoes are crazy. When the White Dew solar term begins to decline.
As the proverb says: "After drinking white dew, the mosquito shuts his mouth" . It is the White Dew season, around the Mid-Autumn Festival on the 15th of the August lunar month, the temperature drops significantly. The dew in the morning is crystal clear, and the low temperature is close to about 15℃. The mosquitoes become convergent from a crazy state and no longer bite people madly, especially outdoor mosquitoes. The indoor temperature is high and you cannot be ignored. Look, a flower mosquito just killed.
Agricultural proverb says: " cold dew days cold dew is heavy, and the frost falls and turns to the thick frost flowers." . This is a portrayal of the twenty-four solar terms. In which solar terms, the corresponding characteristics will naturally appear. This is the traditional culture left by our ancestors. It seems that there is indeed a certain reason. Do you think so?
