How to judge the tilt direction of the earth's axis in the spring and autumn equinox and ask God for help.

When the earth's axis is tilted, the direct point of the sun constantly moves between the Tropic of Cancer and the Tropic of Cancer throughout the year. When the direct point of the sun is on the tropic of cancer, it is summer in the northern hemisphere and winter in the southern hemisphere. If the point is directly on the tropic of Capricorn, the opposite is true.

The earth axis is not inclined, but perpendicular to the surface of the revolution orbit. The direct point of the sun is always on the equator in a year, and the same area is always in a season.

So we can't judge the vernal equinox by the tilt direction of the earth's axis.
