The Longji Rice terraces were mostly built during the Ming Dynasty. They are popular because the terraces looked like scales of a dragon. This is where the rice fields got their name. Longji means “Dragon’s backbone”.
Agriculture was the main reason the terraces were built. Locals aim to make good use of the areas arable land. The terrace system allows enough water to be trapped in each puddle to ensure best rice growth while excess water trickles down to the lower puddles.
