On my previous trip, I met a mushroom wall crack on my way and recommended it to me. So I took my luggage to the Three Gorges Museum on the morning of leaving Chongqing. It's good that the museum can deposit luggage, but I'm so upset that I can't find the gentle slope and climb the stairs directly with my suitcase. The first floor of the Pavilion shows the history of the Three Gorges, its formation and evolution, human activities, myths, historical stories, the process of immigration and relocation, and the protection of the cultural relics of the Three Gorges. The exhibition hall on the second floor introduced the historical development of Chongqing in detail. Especially the small cities with a population of about 250,000 and a mountain city of only 5 square kilometers a hundred years ago had to marvel at the speed and scale of its development, and outsiders expressed envy and jealousy.
