How to see what solar terms are there from the orbit of the earth's revolution?

The earth's orbit is elliptical. The closest point to the sun, that is, the perihelion, is the solstice in winter, and the farthest point is the solstice in summer, depending on the direction of the earth's movement. The midpoint from summer solstice to winter solstice is the autumnal equinox, and the midpoint from winter solstice to summer solstice is the vernal equinox.

In addition, perihelion has the fastest revolution speed, while apohelion has the slowest revolution speed.
