Introduction to the Mine Garden: The Mine Garden is the recycling of industrial relics. This pit already existed before the construction of the park. In the early days of the founding of the People's Republic of China, steelmaking technology was limited, and many important metals were preserved in scrap steel slag. Nowadays, people use these steel slags It was dug and refined again, thus forming the current slag pit. The park constructs the slag pit in the form of a bonsai garden. The bluestone mountain, the "Flower of Steel" landscape wall, the "How Steel is Tempered" relief, stone house garden, half pavilion, and fish bone planting belt are all exquisite and beautiful. . The most special thing is that after the water in the creek combines with the slag at the bottom of the creek, it remains blue-green all year round, as if you have walked into Jiuzhaigou.
