Exhibits include all kinds of animal specimens, mineral specimens, human skulls, dinosaur fossils... Museum of the popular supernet. Especially the famous gems and minerals in the exhibition hall, European royal jewelry, Napoleon gave the queen the crown and necklace, transparent, blue, yellow diamonds, sapphires larger than eggs, rubies, emeralds, cat eyes, pearls, crystals, are blind. The treasure of the town hall hopes that the most dazzling baby in the whole hall will be placed in a conspicuous position at the entrance, and it will slowly rotate in the large glass cabinet. I didn't bring a camera that day, and my mobile phone was shooting at it, and I couldn't catch the dazzling scene. I am most impressed that even two or three-year-old babies in strollers are pushed by adults. Visiting museums is a way of life for many Americans. Since it is impossible to visit the wild animals in the world in person, visit the Nature Museum, observe from multiple angles at close range, understand the earth's creatures, and establish the awareness of loving the earth from a young age, which is worth learning from domestic parents. The museum has free wifi, which is a unified signal for the Smithsonian Institution museum group. It can also be found outdoors, but it is easy to break after the distance is far away.
