Go to Work or Stay Home Before Entering University?
　　In China, it is traditional for us high school students to attend university after we graduate from high school for about three months. Some students will use these three months to stay home for relaxation. However, other students will prefer to do temporary work rather than stay home.
　　Personally speaking, I will use that time to gain work experience, because going to work before entering university has many advantages.
　　First of all, not only can it help us to make money, but also to broaden our view. Secondly, it is helpful for us to figure out the most desire major we want. If we work before entering college, we can have a clearer mind for ourselves. We have more chances to make a right choice; In addition, it can make us treasure our school life more. Life is not easy. When we work, we can realize this. Having tasted the bitter, we will treasure our happy life more. 
　　In summary, it is a chance for us to see ourselves or the world better, so I will go to work before entering university.
