Taijiang mangrove forest in Taiwan was an important port for those crossing the Taiwan Straits. It reflects the historical and cultural development of Taiwan. Offshore sandbars near Tsang Man Stream formed junctions of small and large lakes. Some have silted due to sand accumulation. Mangrove forests thrive in estuarine areas and convert nutrients into biomass. Print molds using 3D printing technology and use metal materials as electrode materials to conduct electrolysis experiments in the Qingkengshan circular salt field, aiming to solve local pollution problems and restore mangrove forests.
