The corridor windows at the Hangzhou Entel Foreign Language School look a bit different from other schools. They are all decorated with beautiful paper cutting art. But they are not just for decoration. They are also to stop birds from flying into windows. Chen Zitong, 14, a Junior 3 student at the school came up with the idea. In early January, she wrote a letter to the headmaster and suggested this. She often saw birds fly into the clean windows and get hurt. After some online research, she found this solution. "Some people decorated windows with stickers or posters. Then I thought of replacing them with our traditional paper cutting art," Chen said. To Chen's surprise, the headmaster took her advice. The school organized a paper cutting art competition. Students' works that got awards were pasted on the corridor windows. In fact, there have been paper cutting art classes since 2011. "We have classes once a week for a month to teach paper cutting," said Fan Ming, an art teacher. The teaching building even has a display wall to show students' works. Through the class, Shi Jiawei, 14, fell in love with the art of paper cutting. "It's very fun. I can design my own patterns and present interesting things through it," she said. She created many works like bears and magpies . Paper cutting also helps students become more patient. Wang Yiyou, 12, was once an active boy. But now, he can carefully design a delicate paper cutting work with scissors and gravers . "I am so proud that I can make it look perfect," he said. (By Wu Qian, 21st Century Teens Staff)
