The most important feature of American universities is to carry out general education and let students develop freely, which is the most basic requirement of education. University education is not only the education of a certain skill, but also can broaden students' horizons, which is one of the obvious differences between American education and China education. The compulsory core courses in universities include a lot of literature, history and philosophy, so American college students are very eloquent, and there are also many eloquent speakers at common campus parties. However, when it comes to the basic knowledge of science and engineering, such as mathematics, physics and chemistry, students in the United States who don't go to graduate school in the future are generally worse than those in China, because American college students don't spend much time doing many exercises in middle school, but prefer to enjoy nature.
