Photo taken on Aug. 8, 2021 shows farmers maintaining a pond at dawn redwood forest in Linhuai Town, Sihong County, Suqian City, east China's Jiangsu Province. Local farmers adopt a complementary breeding model of dawn redwood forests and crab ponds, which can not only guarantee the water quality of the ponds, but also protect the local ecological environment. The income of crab raising per mu of the dawn redwood forests exceeds 5,000 yuan, which helps efficiently increase local farmers' income. (Chen Yu/Guangming Picture)
