There is a saying in the countryside that "sleeping in an alley is what Guanliu fears most". Why are you most afraid of direct flow?
Direct traffic? Produced in some alleys or passages, there is a gap between buildings or between two walls. When the wind passes through these gaps, the blowing wind makes people feel particularly cool because of the accelerated airflow.
In the past, because there was no air conditioning, electric fans were also luxury goods. Therefore, the best way to enjoy the cool in hot summer is to sit in the streets and alleys, which makes people feel particularly comfortable. But this kind of straight flow can't be blown out.
If you sleep in a place with ventilation, you really feel comfortable when you fall asleep, but you will be sore all over when you wake up. Moreover, some people have poor physical resistance, and they may catch a cold when they wake up after a sleep, which is caused by the through flow.
Because the temperature in the through flow is low, it is very harmful to human body. Sleeping in such an alley, blowing wind will cause cold into the body. Mild physical pain, serious illness. So the old people say that cross-flow is the most poisonous!
This proverb is an experience summed up by the older generation in their lives, and it is still very practical even now. Only now there are fewer and fewer people living in the countryside. Even in the village, many people have installed air conditioners at home, and fewer and fewer people will go to the alley to blow.
Is there a second part to this proverb? Bathing is most afraid of bridge water? , the so-called? Bridge heart water? It actually refers to the water under the bridge. In the past, people liked to bathe in the river in summer. Because of the temperature difference, the water under the bridge is particularly cold.
Although the water under the bridge feels particularly comfortable when it first touches, it is easy to cramp and dangerous because of the large temperature difference.
