What constellation among astrologers has the most people?

Yes I think Aquarius and Scorpio. Water bottles are more suitable.

Aquarius not only has a pair of eyes to see the essence of things, but also has high attainments in metaphysics. Uranus, the ruler of Aquarius itself, is astrological. Scorpio is mysterious, but for astrology, it may be blinded by its own strong emotions. Without the calmness and self-control, objectivity and mind of Aquarius, it will not last long. Be careful that sometimes negative emotions will affect the results of astrology.
