I liked airplanes from the childhood. So, I entered the air force after graduated high school in 1992. I got a certificate about maintenance airplane while worked a soldier as a mechanic for aircraft in 1994. I joined the Asiana Airlines after immediately finished my military service in 1995. After 7 years, I entered a college. I studied the design of a machine, again. (I had studied the design of a machine when a third year-student in high school.) Then, I graduated in 2005. Also, I married my wife on april 17 2005. After that, although we don't enough money, have been happy mind. That's all.
