This district is located in southern Keelung City. The Keelung River runs through this district at Dingnai Village from Sihjiaoting of Taipei County. It then turns southwestwards into Banan Village and enters the Qidu District. In addition, the Dongshih River and Xishih River converge into the Nuannuan River here and then flows into the Keelung River under the Nuannuan Bridge. The Keelung Mountain stretches on the north bank of the river and is the junction of the Renai District and Anle District. The Gueitou Mountain stands at the center of the district between the 2 villages of Badu and Nuantong and stretches southwards towards Dongshihkeng. The railway of the Yilan Line separates at the Badu Station and heads towards Yilan and Suao via Nuannuan, connecting with the North-link Line. The Rueiba Highway and the Freeway are connected with the Provincial Highway No. 1 at the Badu Interchange. Also, the Wanruei Overpass Interchange links the Northeast Coastal Road at Nuannuan District, providing convenient transportation.
This district is located in southern Keelung City and borders with Rueifang Township of Taipei City to the east, Qidu District of Keelung City at its west, Shihfengliao of Pingxi Township to its south and Renai District of Keelung City to its north. Nuannuan District contains past settlements such as Dingnai, Dongshihkeng, Xishihkeng, Nuannuanjie, Badu and other places. When the Nuannuan District was first founded on Feb. 1, 1949, there were only 7 villages. Up until Aug. 31, 2013, it had 13 villages and a total area of 22.8283 KM2.
Most district citizens have lived here for generations. As for the population increase in recent years, most of them are those who live at the Guogang Road dormitory of Keelung City Government units. In recent years, due to urban land consolidation, the successive completion of freeway interchange and Wanruei High Speed Road, and the construction of various public facilities, a great number of external population have moved into Nuannuan District, resulting in the abundant construction of high-rise buildings, skyscrapers, and building houses. We believe that they will become the residential area with the most beautiful landscape of Keelung City.
