Why is there a so-called "fight" phenomenon on people's fingers?

The most important thing is that it is composed of gene sequences. This is one of the signs of human identity.

People have ten fingers, and fingerprints can be roughly divided into two categories: one is threaded, commonly known as "bucket", and the other is open, commonly known as "dustpan". In my grandmother's grandmother's time, some people said that the "fighting" on a few fingers could determine the fate of my life. For example, "One bucket is poor, two buckets are rich, and three buckets are pawnbrokers ..." Is this credible? Of course not. In the past, a psychologist, Zhang Yuexiang, made an interesting survey all over the country and found that opinions from different places were completely different. The above is the view of Anhui Province, Hubei Province and Hunan Province. When you arrive in Jiangsu, you will become a beggar. The story about nine fights and ten fights is even different. In Jiangsu, it is "nine fights between the official ship and the white horse." Hunan is "a big official with nine fights and ten fights." Hubei is "nine fights and ten meals in prison" and Zhejiang is "nine fights and ten begging". Therefore, this idea of using buckets to decide one's future seems to be a fabrication and an ancient superstition. However, just today, some fortune-telling pamphlets have been published, which continue to promote the view that buckets determine the future. Of course, this is absolutely groundless.

It should be pointed out that fingerprints are fixed at birth and will not change in old age. And everyone's fingerprint details are different, so it can be said that it is difficult to find the same fingerprint in the world. So in ancient China, in the Shang and Zhou Dynasties, there were documents with fingerprints. Since the Tang and Song Dynasties, fingerprints have been widely used when making documents and signing contracts, because it is the most reliable seal. Until 19 1 1, President Sun Yat-sen also instructed: "Everyone is different, and he will not change for life. No matter how clever and deceitful he is, he will never cheat. " 1949, after the establishment of People's Republic of China (PRC), the fingerprint analysis methods were further unified.

Fingerprint is one of the important clues for public security personnel to solve crimes. After the case occurs, it is necessary to obtain the fingerprints left by the criminals when committing the crime, which can be used not only to examine the suspects, but also as evidence of the crime.

It should be pointed out that the understanding of fingerprints abroad was in the middle of19th century. 1892, Argentina solved a murder case with fingerprint identification for the first time, which caused a sensation. All countries in the world have begun to attach importance to fingerprints and regard fingerprint identification as an important evidence for judging a case.

Because everyone's fingerprints are different, in the computer age, scientists invented the fingerprint security lock, and fingerprints became the key. As long as you press your finger on the recognizer, the computer can quickly recognize the fingerprint to determine whether you should open the door. If you have a fingerprint lock at home, you don't need to bring a key as long as you input all the fingerprints of your family into the computer. Everyone can open the door with a touch, which is very safe. Don't worry about losing your keys.
