In classical astrology, there is a meaning of "two constellations", namely Sagittarius, Gemini, Pisces and Virgo. Because these four constellations represent the transition of spring, summer, autumn and winter respectively, they represent a changing transition state. According to classical astrology, if 1, 7, and 4 are in these four constellations, it will have a changing influence on marriage.

Because 1 house stands for itself, the 7th house stands for spouse, and the 4th house stands for family, especially if 1 or the 7th house is headed by Gemini or Sagittarius. Among them, the seventh house is in Gemini, which means that the concept of marriage is relatively weak, or because they don't know each other very well, they get married in a hurry and then separate because they know each other; The head of the first house falls in Sagittarius, indicating that there are too many expectations or idealizations for marriage, or they decide to break up because they can't stand the bondage of marriage.
