When I was a child, I spent more than ten years learn the violin. Therefore, I couldn’t understand “real music”. After I graduated at high school, a friend of mine suggested that we started to learn the guitar because we all thought it was cool. I will never forget the day on that we went to buy guitars in the guitar store. There I saw a guitar player playing the guitar, which I really enjoyed, and he became my the first guitar teacher. It took me such a long time choose a guitar among several wonderful model. Now the guitar is the most importantly part of my life and I practice it every day.
