Art in safe hands 1 Good evening, ladies and gentlemen. I'm Zhan Haojing, a high school student. I'm also a puppet performer. Look at this puppet. If I move my fingers, it will come to life! 2 I was born into a family of Minnan puppet performers. My grandpa and my mum are both among the best. When I was little, I loved the amazing stories they told with their hands. However, things changed when I became a teenager. I felt less close to the art because people thought puppets were old-fashioned. I didn't want to take part in the performances unless I was asked to. 3 One day, my mum showed me a video of a performance by my grandpa's teacher. The beautiful puppets and their exciting movements amazed me. I suddenly remembered how much I loved this art. I posted my doubts online: “Well, should I continue?” To my surprise, the post was flooded with warm answers. Many people expressed their love for the art and encouraged me to hold on. A truth hit me – it was my responsibility to keep the art alive because the love for puppets was in my blood. 4 The art will be popular again if young people are interested in it. So I held a puppet show at school. When I finished, I saw something surprising: the students were completely lost in the show. Their eyes were glued to the puppets. After a warm cheer, they came to ask where they could see more. 5 The positive reply from the young viewers gave me more courage. Since then, my puppet shows have drawn more attention both from home and abroad. With more and more people joining in, I believe the magic of this traditional art will last forever!
