The Dalongdong area has been commercially developed since the late Qing dynasty during the Qianlong era. With the changes in waterways during the Japanese colonial period, the riverside gradually transformed, bringing new development opportunities to the local area. During the Japanese colonial period, for administrative convenience, the streets and villages had "baozheng" (similar to modern "li zhang" or neighborhood chiefs) to convey and execute official administrative measures. This historical building was constructed in 1929, the same year as the village office. Originally, it served as the assembly hall for the baozheng of Dalongdong during the Japanese colonial period. After the retrocession of Taiwan in 1945, it was used as a household registration office, and later converted into the Daxin Community Activity Center. In 1999, as part of the Dalongdong Old Street renovation project, it was renovated to serve as the Dalongdong Cultural Museum. This unique Japanese colonial-period building in the old district showcases historical materials and artifacts related to Dalongdong and occasionally hosts special exhibitions.
