For the exploration of history, we are always on the road of continuous progress, of course, in the thousands of years of cultural history, we have had enough cultural accumulation, but with the passage of time, it seems that the truth we can see in this is more and more blurred, and with the development of archaeology, history seems to be beginning to appear in front of us again. And in 1992, Yangzhou found an ancient tomb, when after the relevant departments reported, archaeologists also immediately arrived at the scene, after the preliminary study of the ancient tomb, it was determined that this should be an ancient tomb in the Eastern Han Dynasty, and at this time it was already devastated.
In May of the same year, the excavation of the tomb really began, and in the whole process of exploration, almost a lot of funerary items have disappeared, obviously there have been many traces of theft here, and at this time the experts found a rusty bronze, which at first glance seems to be worthless, but this shocked all the archaeologists. This thing is a vernier caliper, to say that it can be found in the tombs of the Eastern Han Dynasty, it seems to be an impossible thing, is it the tomb robbers left here early? Obviously, these are not correct, and after the final comparison, it was found that this is the thing of the Eastern Han Dynasty, named after the "Eastern Han Bronze Caliper".
To say that in the whole world before, almost all people think that this vernier caliper was originally invented in Europe and the United States, and this archaeological discovery can be described as subverting the entire human cognition, and his existence is more than 1,000 years earlier than Europe and the United States. To say that this caliper still has a certain similarity with what we use now, one of his fixed rulers is 13.3 cm long and 0.9 cm wide. To say that this has always been a very high precision instrument, unfortunately, after so many years, the scale and inscription on the ruler have been quite blurred, and in the identification, it was found that he was finally determined to be from the time of Wang Mang.
To say that this cultural relic found from the tomb of the Eastern Han Dynasty is worth cheering for many of us, the mainland, as one of the four major ancient civilizations in the world, can be said to have made great contributions to the world, and these are the fruits of our wisdom. The advent of this treasure can be said to be another proof of China's wisdom for us, at the beginning Europe and the United States still swore that this is their masterpiece, but this archaeological discovery really does not allow anyone to question, I think his discovery is a good news for the whole world, for our Chinese is also a pride, those doubts should also be drawn to an end.
