Now, when the vernal equinox is in the solar terms, where is the sun?

The vernal equinox usually refers to the moment when the sun's ecliptic is at 0, which is around February 15 of the lunar calendar every year (about March 20 to 2 1 in the Gregorian calendar). It also refers to the position where the sun is located between longitude 0 and 15 of the yellow longitude.

One of the 24 solar terms. The sun passes through a period of 0 ~ 15 on the ecliptic. About 15? 2 days, from March 2 1 day (or 20th) to April 5 (or 6th) every year. In a narrow sense, it refers to the moment when the sun passes through the intersection (ascending intersection) of the equator and longitude 0 on the celestial sphere, that is, March 2 1 (or 20). This moment coincides with the vernal equinox, also called "vernal equinox".

On this day, the sun shines directly at the equator, and the world is almost as long as day and night. After that, the position of direct sunlight moved northward, and the days in the northern hemisphere were long and the nights were short. Astronomy stipulates that spring begins in the northern hemisphere. Overwintering crops enter the spring growth stage.
