This incident dates back to the Qianlong period, when there was a mountain in Xinjiang called Maitreya Daishan. This mountain is rich in Hetian jade. Since the Han dynasty, people have been mining here, and then they have mined palace jade and commercial jade here for thousands of years.
Milwaukee has the reputation of being full of jade, and there are countless jade. The peak of jadeite mining is the Qing Dynasty, especially during the Qianlong period and the late Cixi period. Gan Long has carried out six large-scale mining in Milwaukee, the most famous of which is the mining of a piece of Hetian jade weighing 5 tons in Gan Long.
It took thousands of people to transport it back to Beijing, and it took another three years to transport it back to Beijing. Finally, it was carved into a map of Dayu water control. This giant Hetian jade alone wasted people and money, but Emperor Qianlong still felt that it was not enough. Qianlong heard that there are three precious stones in Milwaukee, the heaviest one is 10,000 Jin, and the smallest one is more than 3,000 Jin, accounting for more than 20,000 Jin.
Now a big truck can transport it, but in ancient times, the roads were not smooth and the equipment was incomplete, so it was very difficult to transport it entirely by manpower. Qianlong ordered the jade to be shipped back to Beijing, and the people naturally dared not disobey. It is very difficult for them to take down the stone just from an altitude of more than 3000 meters. Later, it was delayed for a long time because of road problems.
In ancient times, people and livestock could only be used to drag it. After Qianlong's death, Jiaqing ascended the throne for three years, and these stones are still in Wushtala. Jiaqing saw that farmers were very hard. Wherever they went, they had to requisition a large number of migrant workers and provide food locally. People died of hunger and fatigue on the way. Then he ordered the delivery of jade, and there was no need to worry about where it was shipped.
