The terraced fields are built along the slope winding from the riverside up to the mountain top, the highest part being 880 m in elevation while the lowest part is 380 m. The coiling line that starts from the mountain foot up to the mountain top divides the mountain into layers of water glittering in the sun in spring, layers of green rice shoots in summer, layers of golden rice in fall, and layers of silvery frost in winter. The terraced fields were mostly built during the Ming Dynasty, about 500 years ago.
Longji (Dragon's Backbone) Terraced Rice Fields received their name because the rice terraces resemble a dragon's scales, while the summit of the mountain range looks like the backbone of the dragon. Visitors standing on the top of the mountain can see the dragon's backbone twisting off into the distance. In an early morning, when the weather is fine, the sunrise on the summit of Longji Rice Terraces is magnificent.
They are often considered most beautiful in early June. At this time, water is pumped over the rice paddies and young plants are transferred to the main terraces.
