After visiting the Yellowstone Museum, I realized that the city was built because of metallurgy and developed because of mining. There are pits on the first floor of the museum, and you need to bend over to enter. A person feels lost in it. In addition to a table tennis exhibition hall, are all mining exhibition hall, introduced Yellowstone from the Neolithic era to the current mining development, but also let me understand mining for the first time. The museum is next to the People's Park, next to the Science and Technology Museum and the Planning Museum. You can visit together, but you must pay attention to not entering after 16:00. In addition, the locker at the door sometimes cannot be opened and needs the help of security guards.
