The three months with strong water are October [Hai], November [Zi], and December [Chou], which is winter. In the horoscope fortune-telling theory, when the sun is prosperous and declining, if you are born in winter, it is defined as the water season. However, December is wet soil. Because it contains soil, the water in December is weaker than that in October and November. If the stems and branches of the zodiac have more water, or the earthly branches and Haizi Chou are complete, and the heavenly stems are permeable to water, the Chou will become watery.
