Where did the Western Zhou Dynasty micro-engraving technology come from?

With practice, some myopia can improve your eyesight several times. This is consistent with the effect of China traditional Wushu on improving people's eyesight through exercise. This shows that it is possible for human naked eye vision to achieve the function of magnifying 5 times. There are similar records in China ancient literature. There is a story in Liezi about Ji Chang learning archery, saying that Ji Chang learned archery from Wei Fei, an archery expert at that time. Wei Fei first taught him to practice "not blinking", that is, not blinking. Ji Chang would lie on his wife's loom every day, letting the shuttle shake in front of his eyes. Two years later, even if you use something to sweep his eyelashes, it won't make him blink. Then Wei Fei asked him to learn "seeing", that is, "seeing the big from the small, seeing the small from the small." Ji Chang hung a louse on the window and stared at it every day. Three years later, lice were as big as wheels. Ji Chang looks at everything else, just like a mountain. So I shot the louse with an arrow, and the arrow hit the center of the louse, while the rope hanging the louse continued. Some people think that the content of Liezi is fable rather than historical fact, but this story can at least show that in the Spring and Autumn Period, people have realized that eyesight can be improved through exercise, and archery needs to be higher than ordinary people's eyesight. The Book of Songs Gongliu records the historical fact that Zhou people moved with bows and arrows, which proves that Zhou people have the custom of archery, and it is not unusual for some of them to have extraordinary eyesight. Just like there are pilots with better eyesight today. In addition, modern medicine has found that some fundus diseases, such as the late stage of retinitis and the early stage of scabbing of macular disease, can make people see things several times larger than the real thing. Therefore, it is entirely possible that there was an individual whose eyesight was more than five times higher in the Western Zhou Dynasty. Then, it is not surprising that these people carved Oracle Bone Inscriptions with existing copper needles at that time. CCTV has also broadcast that some contemporary micro-sculpture artists can create micro-sculptures without a magnifying glass, which is enough to prove this point. What's the use of this kind of micro-engraved Oracle characters in the early years of the Western Zhou Dynasty? First, analyze the contents of this batch of Oracle Bone Inscriptions. According to experts, the contents of these 393 pieces of Oracle bones are mostly about the relationship between Zhou Dynasty and Shang Dynasty, the explanation of the mystery of Oracle bones carved in the 28 th year of Western Zhou Dynasty ● The hunting of ginger, Oracle bones and so on. As we know, Zhou Wenwang was imprisoned by Shang Zhouwang in his later years and returned to Xiqiao after his release, trying to prepare for the destruction of his business. In addition to developing power, it is also essential to visit talents, study the relationship between Zhou and Shang, and spy on the whereabouts. Of course, all this needs to be recorded for comprehensive analysis, and such records must be kept strictly confidential. Therefore, carving the above contents on Oracle bones was the best scheme at that time. Oracle Bone Inscriptions is also called a spell in academic circles, which means divination. Shang people believed in ghosts and gods, and all major events had divination. The record of divination is Oracle Bone Inscriptions. Zhou Wenwang lived in the late Shang Dynasty and had a high official position. Of course, he knows everything. Divination was carried out by people who were then known as the history of witchcraft. Witchcraft history is a hereditary lifelong responsibility. They not only do divination, but also observe astronomical phenomena and often hold religious ceremonies. These are all done under the high concentration of thoughts. After a long time, it is possible to improve vision, and there may also be scenes in which the medical history of individual witches becomes larger when fundus lesions occur. These phenomena can't be explained in today's Western Zhou Dynasty, but will be regarded as the embodiment of divine power. Zhou Wenwang and others took the opportunity to order them to engrave divination words and the political situation at that time, which was an absolutely confidential measure at that time. And mysterious, it is easier to create a sacred aura in front of everyone. Finally, the unearthed sites in Oracle Bone Inscriptions can also explain the problem. During the period of Zhou Wenwang, Fenghao was the capital, and the political center of Zhou people had moved eastward. However, its birthplace is the place where more than ten generations of Zhou people have lived for a long time since Gongliu, and it is also the location of their tombs. During the Shang and Zhou Dynasties, people paid special attention to ancestor worship and blessing. His father was killed, imprisoned, attacked Zhou, and then there was the Guancai rebellion. In such turbulent times, it is reasonable for Wang Wen to send these micro-engraved Oracle Bone Inscriptions to Zhou Yuanling instead of Kyoto to beg for protection. In the early years of the Western Zhou Dynasty, it was only more than forty years from King Wen to Kang Wang (according to the First Volume of General History of China), but it was a crucial moment for the Western Zhou Dynasty from destroying merchants to consolidating political power. In the meantime, there were frequent disturbances, so that the Duke of Zhou established a Zhou in Luoyang to manage Yin stubborn (adherents of Shang Dynasty). It is reasonable that these Oracle bones are still preserved in Joo Won?. To sum up, the inscriptions on the Western Zhou Dynasty unearthed in Joo Won? should be a miniature version of the National Archives in the early years of the Western Zhou Dynasty. This nature determines that they are not for ordinary people, but only top secret documents kept and interpreted by a few people.
