Who can talk about "precession" and "precession" in a popular and comprehensive way?

Precession is that foundation of earth science! Only the differential rotation of the earth will lead to precession.

Experiments prove that precession of the earth axis does not exist! The precession of the earth's axis is a realistic version of The Emperor's New Clothes! It is against common sense to solve the precession of the earth's axis!

Common sense; The solar terms difference between the northern and southern hemispheres of the earth 180. However, the two ends of the precession of the earth axis move in opposite directions.

In other words, if the northern hemisphere sees the vernal equinox moving westward, then the southern hemisphere sees the vernal equinox moving eastward. Look at the picture below; The vernal equinox in the northern hemisphere moves westward and the vernal equinox in the southern hemisphere moves eastward, so the solar terms in the northern and southern hemispheres cannot guarantee a difference of 180. It is against common sense to solve the precession of the earth's axis, isn't it ridiculous?
