Has the constellation really changed?

Yes, from the perspective of the vernal equinox of the earth, due to the eccentric angle of the earth's axis, the revolution of the earth and the operation of the solar system, the vernal equinox of the earth will change 30 degrees relative to the sun around 2000. This is a constellation. This is Heliocentrism's astrological view, which has nothing to do with what we generally think of as constellations.

At present, the constellation determination method we adopt is geocentric theory. The so-called constellation is the sun constellation, with the earth as the center and the ecliptic on which the sun falls relatively.

The position of the vernal equinox of the earth has nothing to do with our solar constellation.

Which means you're still a Libra.
