In the Showa period, Di Rui built an international friendly memorial library in Mensi Port to commemorate 15 years of the conclusion of a sister city in Dalian, China, and its German architectural form completely imitated the site of the steamship company built by Russia on the Dongqing Railway. The exterior color is tea and white, which is unique and eye-catching. The library is on the first floor of the restaurant, the library for the collection of East Asian literature on the second floor, and the library for the exhibition hall on the third floor.
