Introduction to Lushun Submarine Museum: Lushun Submarine Museum is a modern three-story building. The third floor is Dalian's first all-steel structure exhibition hall. The development of Chinese submarine culture is displayed through texts and models. The two series, History and World Submarine Culture Development History, mainly introduce the functions of submarines at different stages of development and their role in history, allowing tourists to have a general understanding of submarine culture at the beginning of the tour. The high-tech pavilion on the second floor mainly uses the high-tech effect of integrating sound, light and electricity in four-dimensional space, allowing tourists to feel like they are riding a real submarine to dive into the underwater world, and simulated scenes where they can experience various functions of the submarine through independent control.
