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.

Summary
Think & Share
1. Why do the local people still keep the traditional way of growing rice？
2. In what other way do people live in harmony with nature Give examples.
Because the knowledge is paas down through generations of families, and it suits the natural environment.
The terraces are clearly designed, with hundreds of waterways that connect with each other. In China, for example,we have many such water conservancy projects. For example, in ancient times, there was Dujiang Weir, reasonable flood diversion. After the founding of New China there was red flag canal, which divert water from the Zhanghe River to the forest. It was once called "artificial Tianhe" by the world. The Three Gorges Dam on the Yangtze River has four main functions, including flood control and discharge, and the other three functions are: power generation, shipping and water resources utilization. It is one of the largest water conservancy buildings in the world today.
