The productivity of ancient people was relatively low, and they did not pay special attention to education. In society, only scholars can read, and many people can't write their own names at all. It is difficult for people to sign in court, but it must be confirmed, so people have come up with the method of fingerprinting, which is not only suitable for illiterate ordinary people, but also a practical method everywhere.
The ancients divided fingerprints into two categories, one is called? Snail? It refers to vortex fingerprints, and the other one is called? Basket? , refers to the mobile fingerprint. Before the appearance of modern technology, the ancients realized that fingerprints were a special place for everyone, so they set up a special institution to collect everyone's fingerprints and put them in files. There were examples of using fingerprints to solve crimes in the Qin Dynasty. Because each fingerprint is different in some places, it has become an important method to establish evidence in ancient times.
The development of modern technology makes fingerprint identification more accurate and fast, but the ancient fingerprint identification technology is also very powerful, which not only solves the problem of low literacy rate, but also adds a point that is more conducive to solving crimes. Therefore, modern science and technology is not only the wisdom of modern people, but also the wisdom of ancient people. Moreover, in ancient times, people thought that pressing fingerprints was a recognition of self-identity, and once they pressed fingerprints, they needed to be responsible for their own words, so pressing fingerprints was also a part of expressing responsibility.
