At present, most of the cultural relics are excavated from ancient tombs and exhibited only after being cleaned and restored by archaeologists. But some cultural relics are special, and modern science and technology can't be copied. The wisdom of the ancients is really unimaginable, so these are precious and special cultural relics. This crystal cup was more than 2000 years ago. It is the Warring States Crystal Cup, which is currently collected in Hangzhou Museum and has the title of the treasure of the town hall. This crystal cup looks very long and ordinary, but it is actually hidden, because this baby can't be copied anyway. The point is that it is not allowed to go abroad for exhibitions, which can be described as a unique crystal cup in the world.

The crystal cup was found in 1990. At that time, some staff found some porcelain at work, but they didn't report it and sold it. After the police investigation, the matter was informed to the relevant departments. After hearing this, the archaeologist went to the scene and continued to dig down where the porcelain was found. When archaeologists dug more than one meter underground, a shiny little thing appeared in the soil. After more than half an hour of cleaning by archaeologists, this crystal cup finally appeared in front of people.

I thought it was a prank of a grave robber, but it was really a cultural relic after expert research. Su, an expert at that time, could not help sighing repeatedly that "this is a national treasure".

It was made about 475 BC to 22 1 year ago. The height of the cup is 15.4 cm, the caliber is 7.8 cm, and the bottom diameter is 5.4 cm, which is very similar to the glass that people drink every day. According to archaeological research, the history of our ancestors using crystals can be traced back to the Peking man period 600 thousand years ago, and a large number of crystal products were unearthed at Zhoukoudian site. In the Spring and Autumn Period, the technology of crystal products has been developed, such as the unearthed products of the zodiac, which are very meticulous in workmanship. This is enough to prove the wisdom of the ancients, which is really amazing.
