Does the constellation have anything to do with heavenly stems and earthly branches?

Heavenly stems and earthly branches, also known as Ganzhi and heavenly stems and earthly branches, or "Ganzhi" for short, originated from the observation of astronomical phenomena in ancient China. Ten-day work: A, B, C, D, E, G, Xin, Ren and Gui; Twelve earthly branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.

Ten heavenly stems and twelve earthly branches are collocated in turn to form 60 basic units, and they cooperate with each other in a fixed order to form the chronology of the stems and branches, which is a method used by ancient people in China to record time, moon and year, and can also be used to predict seasons and divination, which is quite convenient.

The twelve earthly branches correspond to the twelve constellations. Hai corresponds to Pisces, and the solar term is rain, from February 19 to March 20, Aries and vernal equinox, from March 2 1 day to April 19. Unitary corresponds to Taurus, the solar term is Grain Rain, Shen represents Gemini, the solar term is full, but the solar term is summer and noon. The solar term is summer, Chen corresponds to Libra, the solar term is autumnal equinox, Mao corresponds to Scorpio, the solar term is first frost, Yin corresponds to Sagittarius, the solar term is light snow, ugliness corresponds to Capricorn, the solar term is winter, the solar term corresponds to Aquarius, and the solar term is severe cold.

The dates between them are all pushed back one month in turn, and heavenly stems and earthly branches is closely related to our constellation. These are the conclusions reached by astronomers in their long-term observation. These usages existed in ancient China, which shows that the ancients were still clever, and their usages are also very beneficial to our present life.
