Is the constellation change only related to astronomy and can still be arranged according to the original constellation?

Constellation change is to divide the constellation area according to the constellation background, constellation elements and constellation orbit under the condition that the main star is unchanged. In the mid-20th century, for scientific observation, the constellation areas were re-divided. But the horoscope is divided according to the ancient horoscope, which has nothing to do with the modern scientific horoscope. Although the horoscope has been reformed under the influence of modern science and the change of the earth's axis, it does not affect the calculation and prediction.
