Introduction to China's No. 1 Best Mine 1878: To the east of the main hall, there are three buildings: "China's No. 1 Best Mine 1878", "Railway Source 1881" and "Electricity Era 1906". The "sub-exhibitions" of the Luan Museum echo each other and mainly display the development process of China's early mining industry, railway transportation and electric power industry, allowing people to savor Kailuan's rich historical and cultural heritage and appreciate Kailuan's role in China's industrial development. Its pioneering status inspires corporate memory, city memory and patriotic pride.
