The 'Four Elements Isomorphism' system of Yuanyang terraces in Yunnan

The 'Four Elements Isomorphism' agricultural ecosystem of forest-village-terrace-water system is a typical representative of the farming culture of Yuanyang Hani terraces in Yunnan. 'One mountain divides four seasons, ten miles different days', this day we encountered a thick fog that we couldn't see each other within 100 meters, wandering around the fields and villages, waiting for nearly two hours, finally the fog gradually opened, and the mountains and rivers appeared suddenly. For tourists, the terraces are the 'most beautiful mountain carvings', just a piece of art in the aesthetic sense, but for the Hani people in the mountains, the terraces are their livelihood. After the rain falls, it flows through the forest, villages, terraces, and finally returns to the river, repeating in cycles, so that humans and nature can continue to exist, for thousands of generations.
