1943 September 16, when Mao Zedong visited Nanniwan, he came to Jiulongquan specially, holding the spring water and gulping it. Zhu De, Ren, Peng and other revolutionaries of the older generation all drank this kind of water in Nanniwan. To commemorate this period of history, the soldiers and civilians of Nanniwan built this pavilion in 1972 and rebuilt it in 2008. The spring used to be the drinking water source of revolutionary soldiers, and now it is a famous revolutionary spring and tourist resort. In the early days when the 359th Brigade of the Eighth Route Army entered Nanniwan, in order to find qualified drinking water, the officers and men of the 359th Brigade traveled all over Nanniwan to find Jiulong Spring, and Zhou Enlai was personally responsible for sending water samples to Xi 'an for testing. After learning that the water sample was qualified, Nanniwan began mass production.
