But I think the ancient town of Zhusha is the research base of human civilization. It took more than 3000 years to mine cinnabar by hand, with gunpowder, machines, pneumatic drills and modern high-precision equipment. Isn't this the whole process of industrial development in China? The continuous upgrading of mining tools and industrial revolution are the era when China industry entered a new era, which promoted the progress of human civilization. Therefore, the ancient town of Zhusha plays an extremely important role in studying the whole industrial development history.
The Great Wall of the Underground World was formed by mining cinnabar for more than 3,000 years. Digging down layer by layer, each layer 100 kilometers, a total of eight layers, with a total length of 970 kilometers. This is a huge underground maze, and the appendages left by cinnabar have been mined for a long time.
Here, it is an extremely mysterious, precious and rare treasure for studying industry and precious cinnabar.
