Find the side door of the Museum of Natural History. Although the opening time has passed, there are still many visitors waiting in line for security checks. It is said that there are more visitors queuing at the main entrance. We queued for about 20 minutes to enter this free museum. Because it was through the side door, we visited the Earth Geology Exhibition first. There is no Chinese guide, plus our own knowledge in this area is relatively poor, so it is basically a fog. What impresses us here is all kinds of animal fossils and special geological stones, among which all-inclusive animal fossils should be the most variety we have ever seen in our life, while special geological stones shocked us in their strange forms. There are many interactive projects in the exhibition hall of the museum. Some children brought by their parents enjoy themselves here. Maybe they don't know what it is, but some knowledge comes into their minds in play. In addition to the volcanic eruption, there is an introduction to earthquakes, and even a dynamic experience of the Kobe earthquake in Japan. Although standing in a small supermarket setting is not a very strong feeling of space, but there are video replays near the image of the 2011 earthquake in Japan. From the first floor to the third floor, the exhibition hall is very rich in content, we can only rush through the grass tour. Then we came to the hall at the main entrance of the museum. On the way through the hall was the exhibition hall of large marine organisms and animal fossils. Once again, we were shocked by the huge fossils on the walls. When we arrived at the hall and saw the magnificent palace like a church, we were simply shocked by sight and soul. The whole museum is quite beautiful both inside and outside. The exterior walls and windows, together with the carvings in the interior, are exquisite and amazing. The interior of this Victorian building looks like a cathedral. No wonder people call it "Natural Cathedral". It is said that the museum has 20 large exhibition halls, including botany, entomology, mineralogy, Paleontology and zoology, and many collections have great historical and scientific value. This is the sacred palace of the exhibition of natural history. In addition to increasing knowledge, people here understand the importance of knowledge to human beings. In the hall of the museum, there is a huge model of Lianglong skeleton. There are also some huge exhibits around it. One of them is a stone made of wood. Upstairs on both sides of the hall we saw the magnificence of this natural cathedral, with Darwin on one side of the staircase and huge tree rings on the other. This hall is a palace worth appreciating and tasting from that angle, from micro to macro. Even if there is no content of the exhibition, it will take a lot of time to appreciate both inside and outside the building, let alone the rich collection exhibition here. We reserved less than three hours, apparently not enough, so we finally hurried past the most popular dinosaur exhibition hall and left the Museum of Natural History from the main exit.
