How do you say vernal equinox and solar terms in English?

The vernal equinox is the fourth of the traditional 24 solar terms in China.

"Equinox" has two meanings. One is "equal day and night". At the vernal equinox, the sun shines directly at the equator, and the length of day and night is equal.

Another meaning of the vernal equinox is "to divide the four seasons equally". In ancient times, spring was between beginning of spring and Changchun, and the vernal equinox was in the middle of the two solar terms, which just divided spring equally. The English expression of the vernal Equinox is equinox, so the vernal equinox is the vernal equinox.
