Why did I choose my major? (2nd)

There was a story about why I got into the area of Mechanical Engineering. When I was a junior high school student, I did not know much about how many subjects/majors there were and what they did. I just studied very hard for entering a great senior high school day by day like any other third-grade classmates. One day, one of my classmates told me that there was a college boards, and he desired to get the entrance. I thought it was a good opportunity to get an experience before high schools' association tests, so we took the test together. Unfortunately, he did not pass the test, but I did. When I got the entrance, I was not happy at the beginning. Because all of my classmates had the same goal and concept to get into the top three senior high school. However, I was tired to study for those high schools' association tests from morning to night day after day, so I decide to go to the college. And I was assigned to the Department of Mechanical Engineering by the scores.
I have majored in Department of Mechanical Design Engineering in National Huwei University for five years and Department of Mechanical Engineering in National Taiwan University of Science and Technology for two years since I graduated from junior high school. The machinery has played an important role since industrial revolution and has effected the way we live from our daily life to heavy industry. For example, the cell phone and computers peripheral we use today is getting smaller and lighter, it must use the new and accurate processes to make the tiny component. These projects are necessary, and I am interested in solving these problems.
