Is it scientific that the solstice in winter is not cold and the solstice in summer is not hot?

Old people in rural areas often say that "the solstice in winter is not cold, and the solstice in summer is not hot". Is it reasonable?

In fact, this sentence means that the solstice in winter is not cold, and the solstice in summer is not the hottest time. Why? Literally, isn't the solstice in winter the coldest time in winter? Actually, it's not. Whether it is the solstice in winter or the solstice in summer, it has nothing to do with the weather, but with the high angle of the sun.

Since the solstice in winter is not cold and the solstice in summer is not hot, when is it coldest and hottest? In fact, in the 24 solar terms, it is well-founded to say that the weather is sometimes cold and sometimes hot.

It is said that the coldest time of the year is not the solstice winter, but the solstice winter after 3949. In the countryside, there is a saying that 3949 froze cattle to death. 3949 is just between the great cold and the slight cold, and it is the coldest time, so it is the coldest time between the great cold and the slight cold.

When the weather is hottest, it is not the summer solstice, but the big summer and the small summer in the 24 solar terms. These solar terms are scientifically based, and now users can still judge whether the weather is hot or cold in some seasons. There are only three days between the heat and the heat. This weather is very hot, which is the hottest period of the year. So the hottest time is not the summer solstice but the dog days.

In a word, it is very reasonable for the rural elderly to say that the solstice in winter is not cold and the solstice in summer is not hot. Everyone who knows it knows that March 9 is the coldest and it is the hottest in dog days, so don't misunderstand the summer solstice. They don't mean when the weather is coldest and hottest, so don't make mistakes.
