What are the origins and customs of the vernal equinox?

Origin: vernal equinox, also known as "Japan-China" and "Mid-spring Moon" in ancient times. At the vernal equinox, the length of day and night is average, which is the midpoint of spring, and spring is equally divided. It takes 90 days to travel from beginning of spring to Changchun, so the vernal equinox divides it into two parts, hence the name "vernal equinox".

Vernal equinox agricultural activities:

In the northern areas with little rain in spring, we should pay close attention to spring irrigation, water saving and jointing fertilization, and pay attention to preventing late frost and freezing injury; South China still needs to continue to do a good job in drainage and flood prevention. Early rice seedling raising in Jiangnan and Jianghuai areas has started, and the weather changes frequently in early spring. Attention should be paid to soaking seeds to accelerate germination when cold air comes, and sowing in sunny days when cold air ends.
