This image showcases the natural and cultural landscape of a river valley in Southwest China. In the scene, a turbid river winds through, with neatly arranged salt fields and farmlands along the banks, creating a striking contrast between the golden salt fields, green farmlands, and white village buildings. The background features majestic ocher - colored mountains with clear textures, revealing the grandeur and vicissitudes of nature. The village, nestled at the foot of the mountains, has houses in an orderly arrangement, surrounded by lush greenery, exuding a tranquil pastoral atmosphere. As a traditional local industry, the salt fields carry regional culture, and the interweaving of mountains and rivers highlights the unique geographical features of the area. The photographer is Gao Yuan, as noted in the bottom right corner, and the bottom left corner has the logo of National Geographic Chinese Edition, indicating that this is a professional documentary photograph recording the unique natural and cultural landscape of Southwest China.
