A
Have you ever heard of the beautiful terraced fields(梯田) in Chongqing, China? Let me tell you an amazing story about them.
In a village in Chongqing, China, the people are having a wonderful and big harvest(收获). They grow rice in special fields called terraced fields. To use the land well, they also plant corn in the small paths of the fields. When it's the harvest time, the villagers can get a lot of rice and 200 to 300 kilograms of corn as well!
Terraced fields are amazing in farming. Before there were terraced fields, people usually grew rice on big flat areas called plains. But later the smart ancient people in the mountain areas made terraced fields. These fields look like steps and they are very good at keeping water and helping the rice grow well.
Terraced fields are not only useful for farming, but also attract many visitors. Some people even say that the fields look like the "fingerprints" of the land. Isn't that interesting? They are very beautiful and make the place look unusual.
The terraced fields in Chongqing are both a wonder of farming and a natural wonder and a treat for your eyes. I hope you have a chance to see them for yourself one day.
