My ten finger fingerprints are all round, also known as sinus? Okay？

1. Fingerprints are just skin lines, only as characteristics of identity recognition, and have nothing to do with personal fate.

2. Fingerprint is a protruding line on the epidermis. Because people's fingerprints are influenced by heredity and environment, although everyone has fingerprints, they are all different. Reaching out and observing carefully, we can find several types of small fingerprints: concentric circles or spirals, which look like eddies in water, called barrel lines; Some lines are open on one side, just like dustpan, called dustpan-shaped lines; Some lines are like bows, called bow lines. Everyone's fingerprints are different in shape, and the number and length of lines are also different. It is said that two people with identical fingerprints have not been found yet.

3. Fingerprints begin to appear in the third or fourth month of the fetus and form around six months. When the baby grows up, the fingerprint just gets bigger and thicker, and its pattern remains unchanged.
