Paper cutting(剪纸)is a traditional(传 统的)Chinese art. Many people in China stick paper cuttings on their walls or their windows. The paper-cutter uses very simple tools, such as knives and scissors, to cut parts of the paper away. After these parts are cut away, a lovely picture of people or animals appears (显现). Some paper cuttings are of Chinese characters. Others are of animals or plants. People think paper cuttings will bring them good luck. It is very difficult to learn paper cutting. It needs years of practice to become good at this art.
