Imagine mountains wrapped in silver water, shining in the spring sun. Summer s 1 the mountains turn bright green with growing rice. During autumn, these same mountains are gold, and in winter they are covered in s 2 of white frost. These are the colours of the Longji Rice Terraces.
These terraces were built by the local Zhuang and Yao people. R 3 as far as the eye can see, these terraces cover tall mountains, often from the bottom to the very top.
So why did these people go 4 so much trouble to turn the entire mountains into terraces? Firstly, building the terraces meant that they could increase the areas in which they could grow rice. Secondly, the 5 terraces catch the rainwater and prevent the soil from being washed away.
But perhaps what is most significant is the way in which people have worked in 6 with nature to make these terraces and grow rice. The terraces are cleverly designed, with hundreds of waterways that 7 with each other. During the rainy season, it is along these waterways that rainwater moves down the mountains and into the terraces. The sun heats the water 8 turns it into vapour. This forms clouds from which rain falls down onto the mountain terraces once again.
Although modern technology could help produce more crops, these terraces still mean a lot to the local people for 9 traditions hold much value. Today, the Longji Rice Terraces attract thousands of visitors who come to admire this great wonder c 10 by people and nature working together.
