Introduction to Du Gong Lake: Du Gong Lake was originally a naturally formed mountainous reservoir, with more than 80 mountain tops connected by mountains, and 7 small reservoirs distributed among the mountains. There is a perennial spring on the top of the mountain, and the spring water is clear and sweet. On the west side of the lake is Dugong Mountain, which was once the place where Jia Sanjin (Nanling Xiaoxiaosheng), a great scholar in the Ming Dynasty, went into seclusion and wrote books. The first wonder book in ancient my country, "Jin Ping Mei", was born here. Dugong Lake is also a red revolutionary base and a legendary transportation line in the Huangqiutao Anti-Japanese Revolutionary Base. Liu Shaoqi, Chen Yi and other older generation revolutionaries went north to Yan'an from here and lived here, leaving many relics.
