Which solar term indicates that spring has passed halfway?

The vernal equinox indicates that spring has passed halfway.

Spring has three months, that is, 90 days. Beginning of spring is the first day, and the vernal equinox is the 45th day, which happens to be the midpoint of 90 days in spring.

On the day of the vernal equinox, the sun shines directly on the equator, and the northern and southern hemispheres are divided equally day and night. Since then, the direct position of the sun has continued to move from the equator to the northern hemisphere. In the northern hemisphere, the day begins to be longer than the night, while in the southern hemisphere, it is the opposite.
