What are the palm prints of people?

The texture trend of palmprint is complex, and there are three main lines: the big line that wraps the whole thenar to the wrist from the tiger's mouth between thumb and forefinger, that is, the lifeline; A large line extending obliquely to the thenar from the same starting point or a separate starting point as the lifeline, namely the wisdom line; From the root of the little finger, there is a big line that goes all the way to the root of the index finger, which is the emotional line. Everyone has these three lines, in addition, there are some auxiliary lines, and some people don't exist, such as the healthy line that starts near the thenar and extends diagonally to the root of the little finger.
