The Longji Rice Terraces were built by the local Zhuang ethnic group alone. Though there are many large, flat areas in the region, they built terraces on the mountains to have more areas to grow rice. The terraces are cleverly designed, and can wash away the shallow soil. There are hundreds of waterways, along which rainwater moves down the mountains and into the terraces. Today, local people use modern methods to maintain the terraces, and they attract lots of visitors from all over the country. 参考答案： 【新课导入】 ＊Zhuang ethnic minority is the largest minority group of China.
