It turns out that the rising constellation refers to the rising constellation on the eastern horizon at the moment when you and I were born. It is one of the twelve constellations, not a star. However, this "rising constellation" has a key impact. You can regard it as your soul or the rudder in your life.

It is not easy to have too much perception of it when we are young, but its strength will gradually increase after 40 years old, firmly locking in the general direction of life for you. Theoretically, different rising constellations will create different shapes for you, but after the game in which the top ten planets meet in our birth chart, the pressure angle and harmonic angle will distort our original basic model at will.
