Why can someone tell by reading their palms?

The ancients liked to look at faces, which were connected with images. Since ancient times, there has been a saying that the sky is watched at night, but the ancients believed that heaven and man are one, that is, what appeared in the sky would correspond to what appeared on the ground.

Palmistry, on the other hand, infers the information of life by observing the lines of the palm, which is actually a kind of big data statistics. People who are familiar with palm reading naturally know how to interpret it.
