On our final day before flying our of Guilin back to Hong Kong, we had caught the boat back and then a car to the Longji (translating to Dragon's Backbone) terraced rice fields roughly 80kms north of Guilin. They are 650 year old of agricultural heritage, spanning elevations of up to 1,100 meters. Construction began during the Yuan Dynasty (1271–1368) and was perfected over 600 years by ingenious local Zhuang and Yao farmers who developed sustainable irrigation directly from mountain springs. The landscape winds along mountainsides to resemble a dragon's scales.
