What travelers say:

From the museum, we took a short ride, and a building with iron like an Optimus pillar and a wire tower came into view, marked with the red characters of "Yellowstone National Mine Park". The guide took us around the building, behind some bulldozers, cranes, and transporters used for mining. The guide told us that this is a production and transportation sightseeing line created by mining, loading and transporting tools. I watched these machines that once roared on the construction site in a daze, between each car is green grass and green, where is the majesty of the mine that galloped on it? Not far away there was a behemoth, an old steam train, lying quietly there. I look at these machines that have been eliminated, and think about all kinds of mining machinery and high-speed trains today, I can't help but admire the rapid development of science and technology in China in the past 50 years.
