In the journey of nearly 135 years of establishment and development, Dong Xuan market is not only a busiest commercial center of Hanoi, but also a cultural-historical symbol associated with the urban memories of the Capital people. In order to preserve and spread these typical values, Dong Xuan Joint Stock Company in collaboration with the National Archives Center I has implemented a research project and launched a cultural publication "Dong Xuan Market - Memory Space" on October 8, 2025.
