The meaning of harm mostly refers to some feudal superstitions. If a married couple has different horoscopes and different zodiac signs, they will be incompatible with each other, resulting in the death of one or both parties. For example, the white horse offends the green ox, the dragon and the tiger are like knives and files, the rooster and the monkey are not the first, etc. If a child is born with different horoscopes from his parents, and the child has a strong destiny, it is also suspected of overpowering the father and undermining the mother.
