Where was the Kunlun jade in the Central Plains mined in the pre Qin period?

I don't know much about jade, and I don't understand whether the "Kunlun jade" you said was identified by modern people as being produced in Kunlun, or is it said in ancient books that it was produced in Kunlun? If it is identified by modern people as produced in Kunlun, then there is nothing to say, and the Kunlun that modern people say is, of course, the Kunlun Mountain in Xinjiang. If it is Kunlun in ancient times, it will be very complicated.

In short, in ancient times, the mountain "Kunlun" only existed in legends, where it is, which mountain it is, no one can figure it out, anyway, there are many poles. From the present point of view, it seems to refer to some mountain ranges in the area where the Yellow River bends at the junction of Qinghai and Gansu. Later, Zhang Qian sent an envoy to the Western Regions, and went to today's southern Xinjiang region, where he saw a big river,—— which we know today is the Tarim River.

The Tarim River is an inland river that eventually disappeared into the Taklamakan Desert. However, the locals in southern Xinjiang told Zhang Qian that the river had dived underground, and after flowing underground for thousands of miles, it gushed out somewhere in the east and continued to flow to the sea. Zhang Qian thought that after this river gushed out of the ground, it was the Yellow River, so he reported it to Emperor Wu of the Han Dynasty, saying that I had discovered the source of the Yellow River, which was somewhere in the Western Regions.

Emperor Wu of Han looked at the map, and sure enough, it was like this. However, there is a saying in the "Classic of Mountains and Seas", which is called "Kunlun Hill, the river flows out of Yan", which means that the Yellow River originates from Kunlun Mountain. Emperor Wu of the Han Dynasty thought, since the source of the Yellow River has been discovered, then Kunlun Mountain should also be discovered, it must be near here, so he looked at it on the map and found that there was a very large mountain range nearby, so he called it Kunlun Mountain.

This is how the Kunlun Mountains in Xinjiang came about. Therefore, if it was pre-Qin who said Kunlun, it would definitely not be from Xinjiang.

The jade unearthed from the tomb of the women of the Yin Dynasty, identified by modern technology, is indeed mostly Hetian jade, which comes from Khotan. In the Yin Shang era, the merchants had already entered the Central Plains, and it was indeed possible that Hetian jade was brought by the Yu family, which was also known as Youyu, Yu Zhi, and Yueshi.

But the history of the Yin people's use of Hetian jade began as early as the pre-Shang era. "The Biography of Mu Tianzi" mentions that after there were Yin people near the Hexi Corridor north of the Yellow River, Mu Tianzi canonized the Yin people to continue the Yin worship. These Yin people were the remnants of the Shang ancestors who stayed in place after the merchants moved eastward.

During the Xiahou period, the location of the first merchants was roughly in the weak water basin, and the merchants found jade in the lower reaches of the weak water, so they went up the weak water and needed to find jade ore at the northern foot of the Qilian Mountains. Over time, the Qiang people who herded sheep under the Qilian Mountains also had the knowledge to identify jade mines, and these Qiang people were widely distributed in the continuous foothills formed by the Qilian Mountains, Altun Mountains, and Kunlun Mountains, and slowly the Hetian jade under the Kunlun Mountains was developed by the Qiang people. Therefore, under the demand of merchants, a jade trading route was gradually formed, which is the origin of the jade road that spanned 4,000 kilometers from east to west for thousands of years.

Sub-question 1: b

Question 2: Analysis of question C:

Question 1: One of the main methods of jade mining in ancient times was to pick jade from the riverbed, and the jade was deposited on the riverbed, mainly at the mouth of the river, because the water flow slowed down, and was deposited along with the sediment. The upstream is in the mountainous area, the flow rate is fast, erosion is the mainstay, and it is not easy to deposit, so it will not be wrong in the R and H river sections, C and D.

There are only sediment deposits with very small particles downstream, and there are no jade deposits, a mistake. The N section is the river outlet, which is prone to jade deposits, B pairs.

Question 2: The area shown in the map is the northwest desert area of China, and Hotan is located on the oasis at the edge of the desert. Resources, topography, and transportation are all important factors, but they are not the dominant factors, and a, b, and d are wrong.

Kunlun jade, also known as Qinghai jade, is produced in the eastern margin of the Kunlun Mountains into Qinghai Province, and is located in the same metallogenic belt as Hetian jade. The east of Kunlun Mountain is called Kunlun jade, and the north of the mountain is called Hetian jade, and the distance between the two is about 300 kilometers in a straight line.

Kunlun jade has a delicate texture, elegant and refreshing, good oiliness and high transparency. It can be divided into white jade, gray jade, green jade, white belt green, sugar-coated white, etc. The crystal round, pure and flawless, no cracks, no impurities are the top grade.

Kunlun jade is mainly produced in the southwest of Golmud City, Qinghai Province, more than 100 kilometers along the Qinghai-Tibet Highway in the plateau and hilly areas, so far there are about three mining sites.
