See the detailed explanation of the wisdom line of handprint

The wisdom line in palmistry is also called brain pattern, which is an important research object in palmistry. In China, the wisdom line symbolizes oneself, so it is also called "human pattern" by people. The starting position of the wisdom line is the upper end of the thumb on the inner edge of the palm, which is the same as the starting point of the lifeline, extending towards the little finger, usually until the middle of the ring finger and the little finger. This length is actually just right. If the wisdom line is too long, this person is shrewd and cunning and annoying; if the wisdom line is too short, he lacks brains and is even a little stupid.

If the lines of wisdom are deep and thin, it reflects that the person is smart, able to concentrate on doing things, has excellent memory, and is successful in school; if the lines of wisdom are shallow and thick, it reflects that the person’s intelligence is flat and cannot concentrate. His memory is also poor, and he will not get good grades in learning. If the island pattern appears on the wisdom line pattern, it reflects that the person’s brain is vulnerable to trauma, which leads to weakened memory and insufficient concentration of thought; if the chain pattern appears on the wisdom line pattern, it reflects that the person will be affected by external factors in studying. If the wisdom line and the lifeline are at the same starting point, they become one and extend a certain distance and then separate, it reflects that the person's personality is relatively introverted, and he is cautious and able to take all aspects into consideration. However, if the joint part is too long, it reflects that the person's personality is too indecisive and lacking courage.
