The Longyou River flows through Rugao, a county-level city in Nantong, in East China's Jiangsu province. The river was a stinking ditch in the past, but after painstaking restoration, Longyou River ecological park has become a popular leisure space, acting as the city's green lungs and offering a pleasant natural environment.
