Tongluo Ancient Painting Ecological Park is located along the river in Fangniu Village, Nanshan Street, Nan 'an District, Chongqing. Mountains and water constitute a unique natural landscape here. Relying on the unique natural advantages, the steepness will be turned into a stepped trail, and the virgin forest will be turned into a natural barrier. On this basis, facilities such as observation deck and leisure experience area will be added. The cliff of Tongluo Gorge across the river is the gateway to the main city of Chongqing. Known as the "East Hanging Barrier" in wartime, it is a battleground for military strategists in past dynasties. In 2116, Chongqing started the renovation of the Yangtze River and Jialing River, restored the ecological waterfront, optimized the waterfront function, created a hydrophilic space, protected historical and cultural resources, and built an upgraded version of a landscape city. With the support of the government, Fangniu Village wants to introduce a local garden enterprise to manage this "garbage dump". Zhang Shunyin not only runs a garden enterprise, but also runs a restaurant nearby. In the restaurant, he often looks at Tongluo Gorge and sighs: "Such a beautiful scenery has been ruined by this garbage dump." Zhang Shunyin and Niufang Village hit it off, and he took out all his life's business income. Zhang Shunyin said: "I am a Chongqing native who grew up drinking Yangtze River water, and I must do something for future generations. More than three years have passed, and the Tongluo Flower Valley Ecological Park has finally been built. The "garbage mountain" has disappeared, and the Tongluo Gorge is beautiful again, even more beautiful than before.
