The circular trail has a comprehensive view to the entire sugar factory, from which we discover the captivating silhouette and its complete history. As to environmental resources and design skills, the lake signifying the urban hydrological and ecological sustainability is constructed with the drainage system with the springs and the gravel layers. A large volume of groundwater therefore flows towards the construction site. The underground tunnel systems support the growth of aquatic plants and permanent pond that establish the education of urban hydrology, the ecological island, and the habitat for water birds. Secondly, the design is contributed to the cultural regeneration and continuation of the sugar industry, as well as the continuation of railway culture. The layout of buildings and streets of sugar factory, along with the connection between tracks and circulation are considered.
