The vernal equinox means clear and clear without rain.

The meaning of no rain from vernal equinox to Qingming Festival is as follows:

There is no sadness in the warm and humid air flow in the south or cold air does not go south, so there is no rain. This kind of weather will continue for some time, even in Tomb-Sweeping Day. In this case, there will be a spring drought, which is extremely unfavorable to agricultural production.

The vernal equinox has three stages: "wait for the mysterious bird to arrive, wait for the thunder to sound, and wait for the electricity to start." The mysterious bird refers to the swallow, that is, when the vernal equinox comes, the swallow also comes, and the thunder gradually increases, accompanied by lightning. It means that the weather is getting warmer in the spring equinox and solar terms, the thunderstorm weather is increasing, and the lovely swallow has returned to his hometown.

The vernal equinox is the fourth solar term in spring, which is of great significance in astronomy, because the sun shines directly at the equator during the vernal equinox solar term, making the northern and southern hemispheres equally divided day and night.

Moreover, the vernal equinox has another meaning, which is to divide spring into two parts, because the period from beginning of spring to long summer is traditionally called spring, and the vernal equinox solar terms just divide spring equally.

Rural proverbs are as follows:

1. When it rains at the vernal equinox until Qingming Festival, there is no way out when it rains at Qingming Festival: This proverb means that when it rains at the vernal equinox, it will rain all the way to Tomb-Sweeping Day, which means it will be rainy. It indicates that it will rain in Tomb-Sweeping Day, and the roads are muddy and impassable.

2. It's an empty year when it doesn't rain at the vernal equinox, and a good year when it rains at the vernal equinox: it's sunny when it means that it doesn't rain on this day, so this year's grain harvest is not good. On the contrary, if it rains on the vernal equinox, it indicates that this year will be a bumper year.

3. On rainy days in the spring equinox, the spring rain does not stop: it means that if it rains on the day of the spring equinox, it means that the whole spring rain is abundant. On the contrary, if the weather is fine on the day of the vernal equinox, it means that there is less rain in spring and there may be a spring drought.
