The Earthly Branch of boys is Wei, and the Earthly Branch of girls is Shen. Wei contains Tiangan Dinghuo, Shen contains Renshui, and Dingren turns into water. Water indicates the wealth of the two of you living together. If a girl grows up beautiful, the boy will admire her very much, but If a girl is a little squeamish, it will affect your married life; if the girl learns to be more gentle, the marriage will be okay.
