What does the sentence "the north wind blows from beginning to end" mean?

If the north wind blows on the day of the fright, it means that the temperature will be lower in the next few days, and it will be as cold as winter, so be prepared for the cold. Sting means; When the spring thunder sounded for the first time, the insects hibernating underground were frightened, got out of the soil and started the New Year's activities. In fact, the temperature rose, the soil began to thaw, and spring ploughing began. The cold and warm weather in early spring is more likely to conflict with the climate in the critical period. Although the temperature is gradually rising and getting warmer, it will change as soon as it gets cold, and it will feel cold at the end of spring. The cold air drops, the temperature changes dramatically, and some return to the artistic conception of winter.

Of course, this sentence is not universally applicable, but it only removes certain regionality and limitations. Moreover, this proverb is a summary of the natural laws of the past, and the forecast of the future weather based on the summary is actually very inaccurate. From the day of panic, everything revived. The first two solar terms represent that winter goes and spring comes, and the shock is "spring thunder starts to shock and everything recovers". During the period of rain and fear, the weather will get warmer and warmer. Some meteorological proverbs in rural areas are some experiences summed up by rural people in their long-term agricultural production and life. Although these proverbs are regional, sometimes the north and the south may be different, but they are for reference.

When the insects were frightened, the temperature had risen and the insects had come out. But when the north wind blows, we should pay attention to heat preservation and cold protection from beginning to end. After all, tails should refer to animals. It is very cold in winter. For people, there is naturally a proverb "Spring covers the autumn". In rural areas, it is said that the river can only be opened when the spring breeze blows. In other words, the temperature of the weather is good and bad, the spring breeze will blow harder and harder, and the ground temperature will rise slowly. Plants will germinate and grow. However, the weather is ruthless. If it is affected by cold air, it is possible to blow the north wind in Tomb-Sweeping Day, and then bring obvious cooling weather, which is what we call late spring cold.
