The spring equinox is windy until mid-April.

The vernal equinox is windy until mid-April, which means that if there is a strong wind on the vernal equinox, the wind will blow until mid-April, and the wind will stop bit by bit.

The "vernal equinox" means not only sharing the spring equally, but also sharing the length of day and night around the world equally. Theoretically speaking, the global day and night are equal in length at the vernal equinox. The ancients also realized this long ago. Ceng Yun is mentioned in Ming Shi Li Yi: "The dividing line is the point where Huangchi meets, where the sun comes and divides day and night equally." But in fact, there are still some differences between them due to various influences.

The custom of vernal equinox

1, Spring Festival: In many places, there is a custom of offering sacrifices to ancestors at the vernal equinox, that is, praying for the blessing of ancestors with a grand sacrifice ceremony, so as to achieve bumper harvests, favorable weather, people's well-being, peace and prosperity. Some people call it the Spring Festival. Many ancient books and paintings are related to the content of the Spring Festival. For example, Pan Rongbi, a Qing Dynasty man, once said in "Ji Sheng at the Age of Emperor Jingdi": "The vernal equinox and autumn are national gifts, and scholars should not sacrifice them at will." It can be seen that ancestor worship at the vernal equinox originated from the royal vernal equinox.

2, vertical eggs: "vertical eggs" is also called "vertical eggs", which is also a custom of the spring equinox solar terms. It is said that at the vernal equinox, the earth's axis is tilted by 66.5 degrees, just in a relatively balanced state with the orbital plane around the sun. The success rate of laying eggs at this time will be even greater! But we must also ensure that those who lay eggs are bold and cautious, and their hands must be steady. This custom, in addition to the pursuit of fun, also contains people's beautiful vision of "adding more imports".
