Today's science and technology is very developed. In the field of identity recognition, there are many high-tech helpers. With fingerprints, one can identify a person's identity. Even a small piece of skin debris can be used as evidence. The progress can be determined by a hand photo alone, because some scholars have found that the blood vessels in the human hand are the same as the fingerprints, and everyone is different. But what is strange is that in the ancient times when there was no fingerprint recognition, when the ancients signed, they still used the way of drawing to determine their identity. Then why?
As early as the Qin and Han Dynasties, the ancients adopted the system of sealing mud as a measure of confidentiality. At that time, important documents were written on the wooden slips, and the clay was sealed at the end of the rope or at the intersection, and then stamped or fingerprinted as a test. This kind of confidentiality is very reliable and very convenient to use. It is one of the most commonly used secret methods of the ancients. In the ancient city of Milan, Xinjiang, China, the earliest copy of the Tang Dynasty fingerprint contract was unearthed. There were four red fingerprints at the landing, and one of the fingerprints was clear and clearly visible.
In ancient times, according to the fingerprints, although there was a certain contrast effect, in general there was no reliable way to identify similar fingerprints. The main purpose of the ancients according to the fingerprints was to prove that the ancient cultural education was very scarce, many people I can't write, so when there is a need for personal signature, it is like a promise to prove my identity by handprint. As long as the painting is basically no one will deny it. The simple and credible reputation of the ancient society is very important for one, so sometimes a fingerprint can have a farmer's life.
In the Song Dynasty, officials used fingerprints to judge the case. The ancients discovered that the fingerprints of each person were different, and the fingerprints of the same person would not change regardless of how many times they were drawn. There is only one way for the ancients to identify fingerprints. It is recognized by the naked eye. Everyone knows that the fingerprints are threaded and non-threaded. This is the best fingerprint, but there are always some cases that are difficult to distinguish with the naked eye, even if they are the same person. There are certain differences in the fingerprints that are pressed for a long time. Despite this, fingerprints are also the best way to identify identities in ancient times, and the correct rate is still quite high.
