This proverb is easy to explain literally. If it is sunny at sunrise, it is enough to wear a thin coat when you arrive in early winter. This means that if the weather is clear, the temperature will continue to be high, and when it is cold in early winter, it is not cold. Wear only thin clothes in weather when you should wear thick clothes.
This year's beginning of winter time is 1 1.7, and many areas in the north have put on their coats, not to mention the northeast. If you are still wearing a thin shirt, it may indicate that it is a warm winter. It rained for forty-five days. This proverb is also easy to explain literally. If it rains on the first rainy day, there will be more rain in the next 45 days, or there will be more rainy weather in the next 45 days.
Agricultural planting
The pond is full of rain, and there is no grain after autumn. This proverb was summed up by farmers. Literally, it is also from the perspective of agricultural cultivation. If it rains on a rainy day and the pond is full of water, only half of the grain will be harvested in the autumn harvest, which means that the production may be reduced by half.
Why is this happening? As mentioned above, this is a critical period for the growth of corn, soybeans, peanuts, rice and other crops. Whether the filling is normal or not and whether the pods are full depends on the growth situation at this time, so as to ensure sufficient light, which is conducive to increasing yield and improving quality. So judging from the meaning of this sentence, it also means that it rains when it rains (the above content is for reference only).
