I’ve been dancing since I am five. My parents, that were very strict with me, put me in many famous dance studio. I must go to dance almost every day, and only rested in Sundays. My parents wanted me learn every kind of dance so that when he owned my dance studio, I could teach other students. I loved dancing or sometimes they pushed me so hard that I hated it. Anyhow, I thanked them for pushing me and make me an excellent dancer. When I was 20 I opened my own dance studio with their help. Now I’m glad to be able to teach different people what to dance.
