Good morning.
I'm glad to be here to introduce myself. My name is Shang Yun, and I am a seventeen year's old girl. I'm from China and studying in Luqiao High School. My interests include swimming in summer, playing the piano and reading novels. And I also like listening to music in my spare time. I'm a warm-harted girl who likes helping people and making friends. I'm fond of traveling and attracted to different cultures. I've been hoping to travel around the world since I was a little girl. I feel lucky to be here and I really want to show the good qualities of our nation to the world. Please give me the opportunity to make my dream become true by allowing me to go to Germany. Please believe that I'm the most suitable candidate and choose me! That's all, thank you.
(You did a good job already. Hope you can get it. Good luck!)
