I think "spring rain is as expensive as oil" refers to early spring, especially in the Central Plains. Because at that time, it was the time when wheat was turning green, and the next spring rain would undoubtedly be of great help to the growth of crops. But why doesn't it rain?
Anyone with a little knowledge of geography knows that in spring, with the direct sunlight moving southward, the intensity of warm and humid air flow in the south is increasing and it begins to invade the north. When encountering the residual cold air in the north, warm air will rise upwards, condense into water droplets at high altitude and low temperature, and then fall to the ground. This is what we call rain.
So, why is there less rain in early spring? Because the cold air in the north was still "firm" at that time, the warm and humid airflow in the south was still very weak, and it was not easy to form condensed water droplets in the sky, so there was little rain. During the Qingming Festival, the warm and humid air from the south is "strong", while the cold air stuck in the north has reached the end of its tether, and it is easy to see the scene of "rainy in Qingming Festival"!
Who calculated it? There is also an old man who has a clever plan. who is it? Jesus Christ.
According to traditional customs, there is an eternal saying, which is called "planting melons and beans before and after Qingming Festival". At this time, it was raining lightly. Isn't this God's favor to farmers?
Intangible cultural heritage-understanding the 24 solar terms.
Spring rain shocks spring and clear valley days, summer is full of mountains and summer is connected with heat, autumn dew is cold and frost, and winter snow drifts.
This is what I asked to recite in Chinese class in primary school. Twenty years later, I can still recite it backwards.
Now we can easily get the weather forecast for the next day, seven days or even half a month or a month every day. There is also an hourly rain forecast. The scientific and technological level of the ancients is far less than that of modern times. If you only know the way of life of the ancients, you underestimate the wisdom of the ancients!
Everything has rules to follow, and "work at sunrise and rest at sunset" is also a rule. After a long period of observation, the ancients found that a year was regular. For example, the four seasons cycle, and the twenty-four solar terms subdivide the laws of the four seasons, and each season is divided into six parts, gradually evolving into twenty-four solar terms. As for the discovery and exploration of the law, it is also very exciting and rich. You can consult other materials yourself. )
The ancients lacked productivity, and the most important thing at that time was agricultural farming. The ancients who looked at the sky and ate were unable to study the "sky" [chuckle].
The rain in Tomb-Sweeping Day is definitely not calculated by one person, but summed up by the ancients over time.
Qingming is the only day that is both a solar term and a festival. Tomb-Sweeping Day is different from other festivals. It can be said that it is fixed or not fixed every year, ranging from 4.4 to 4.6. Qingming lies between the vernal equinox and Grain Rain, and it is the time to start sowing in a year. Won't it rain?
Compared with the 24 solar terms, most people are more familiar with the four seasons, so we don't wonder why it is so hot in summer and so cold in winter, but why it rains in Tomb-Sweeping Day. Ladies and gentlemen, is this true? [Tongue sticking out]
I suddenly thought of four self-confidences in the previous party class. Twenty-four solar terms are still applicable in 2 1 century. This is cultural confidence!
During the Qingming Festival, there are many rains, and pedestrians on the road want to die. Excuse me, where is the restaurant? The shepherd boy pointed to Xinghua Village.
Tomb-Sweeping Day is full of tears, the flowers are boring, and the glass is floating west. Give the old man a little respect!
These are the commandments left by our ancestors, which have been verified and ruled for many years. Without rules, there would be no Fiona Fang and no ancestors. How could there be people today? Such as rain in Yunnan, hemp fiber in the west of Yunnan, a gust of wind in the east of Yunnan, and black in the north of Yunnan!
That's the truth! Ancestors can see clearly, calculate clearly, remember clearly and speak clearly!
Let's March towards social civilization together! Let's go for an outing to enjoy flowers, appreciate civilization and pay homage to our ancient predecessors!
Who told you that it rained as soon as you got to Tomb-Sweeping Day?
Why didn't you see the rain when you arrived in Tomb-Sweeping Day? I don't know where you are from. You can check the national weather forecast in recent days, and there is rain in a few areas!
I am in Hebei, where there is little rain, and there is not much rain in Tomb-Sweeping Day! There has been a little more rain in the past two years, and it may rain before and after Tomb-Sweeping Day. However, a few years later, it seldom rains in spring. Spring rain is as expensive as oil.
So your problem is probably your own subjective judgment! This argument is untenable. What are you talking about?
I'm Jiang Wei's teacher, and I'm glad to answer your question.
Tomb-Sweeping Day is also called Ghost Festival among the people, which is said by the older generation that ghosts don't tread on dry land.
There is also a saying that the ancestors are sacrificed at Qingming Festival, and heaven and earth share the same sorrow.
In fact, it's all about climate change and increased rainfall before and after Tomb-Sweeping Day, which is just a saying handed down by the ancients in combination with climate and festivals.
In fact, this is similar to a proverb about climate, such as:
In the dog days, the tiles will not dry, and there will be no drought for three days.
Before the thunder, there was no light for forty-nine days.
The rain and thunder in summer are not fierce, and the rain and thunder in autumn are not long.
It never rains in Tomb-Sweeping Day every year, sometimes.
In the past, the old man used to say that it is rare to have sunny days in Qingming and cloudy days in Grain Rain. This is handed down by our ancestors. Every year in Tomb-Sweeping Day, we pay homage to the dead. On this day, I feel that God will shed tears. There is also a saying that it rains in the Qingming period, and pedestrians on the road want to break their souls. Without martyrs fighting for the world for us, there would be no happy life for us today. Every time the tomb is swept to pay homage to the dead martyrs, God will cry and mourn for the martyrs. Let us always remember this day in Tomb-Sweeping Day! Without these revolutionary martyrs, there would be no us today.
I don't know who is right. During the Qingming Festival, there are many rains, and pedestrians on the road want to die. Ask local people where to buy wine? The poem "the shepherd boy refers to the apricot blossom village" is the best explanation. From ancient times to the present, the weather in Tomb-Sweeping Day is not very good every year, either foggy or rainy. Perhaps people's ancestor worship moved the sky.
During the Qingming Festival, it is rainy in spring, seasonal climate and human factors worship ancestors, so it is rainy.
