This kind of personality is naturally suitable for men, because men were representatives of power and symbols of power and force in ancient times. The man with a broken palm represents the strength and independence of the ruler and superiors. I believe that the man with a broken palm can manage his wealth and destiny well, so as to embark on the road of getting rich. This is the interpretation of "the man with a broken palm takes the lead".
It is not a lucky thing that ancient women were labeled as "tough" and "upright". After all, the status of ancient women was far inferior to that of men, requiring women to "take their husbands as the key link". If women are too overbearing and independent, they will offend the authority of men who have the status of head of the family. This is also the reason why most ancient women were gentle and virtuous. A woman's palm is broken, and this kind of character and numerology is naturally not a qualified wife that men dream of.
In a word, the proverb "Men break their palms, women keep the house" is actually a product of the interweaving of palmprint numerology and the ancient social background of China. The same physical characteristics and two different fates of men and women represent the unequal social status of men and women in ancient times.
