Old people often say that "four hoofs are uncertain, and they are bound to get sick." What is the truth?

Old people in rural areas often say,' it will be warm in two spring and one winter'. What does that mean? This proverb is very reasonable. It is accumulated through years of experience. Although it seems dull, it is actually more than just an expression. It is a conclusion that we have reached after calculation on the premise of not paying attention. Our twenty-four solar terms have just been included by UNESCO, which is of great significance and a classic interpretation of our profound understanding of solar terms. It makes sense that two springs and one winter are warm.

It is said that before the Spring Festival in beginning of spring, the Spring Festival is equal to two spring and one winter, which is called two spring and one winter, also known as the double spring year. Spring starts earlier, and the ambient air temperature varies greatly. Also known as "two springs and one winter, winter without quilt", it has always been considered as the standard warm winter statement.

Warm winter is extremely unfavorable to agricultural production, which will reduce rain and snow, and drought is extremely unfavorable to agricultural production. Due to the high temperature, pests and diseases are easy to breed, and crops will also be reduced in the coming year. Therefore, there is also a saying in rural areas that "one winter in Er Quan, ten cowsheds and nine empty ones".

In fact, the real double spring year is not so understood. The real double spring year refers to the lunar calendar. We meet beginning of spring twice a year. In fact, we sometimes pay great attention to the solar calendar, and the double spring here refers to the lunar calendar. For example, in 20 17, beginning of spring is on February 3rd (the seventh day of the first month), while in 20 18, beginning of spring is on February 4th (the 19th day of the twelfth month).
