The custom activity of solar terms in beginning of spring is to erect eggs.

The vernal equinox lays eggs vertically.

Vertical eggs at vernal equinox, also known as vernal equinox eggs, refer to the "vertical egg game" popular all over the country on this day of vernal equinox every year. This China custom has already spread abroad and become a "world game". The ancestors of the Chinese nation began to celebrate the arrival of spring, and the saying that "when the vernal equinox arrives, eggs look good" began to spread.

As early as 4,000 years ago, China had the tradition of dividing eggs in spring to celebrate the arrival of spring. It is said that laying eggs has nothing to do with the vernal equinox.
