Why do you want to distinguish men from women by palm reading?

What ancient fortune tellers said was mostly male left and female right, mainly because of the concept that men were superior to women. In modern fortune-telling, compared with the right hand, the left hand is the congenital lifeblood, and the right hand represents the present and even the future life, so as to make a comparative reference. If there is a great difference between the left and right palms, it means that this person's personality is complicated and his fortune is extremely changeable.
