Argument is the soul of the paper, sub-argument is the skeleton supporting this soul, and argument is the flesh and blood of the paper. It is inconceivable that a person should be full and colorful, with only a soul and skeleton and no flesh and blood. The same paper, with only the central argument and sub-arguments, cannot be called an article. There must also be typical and vivid arguments.

Typical arguments refer to representative examples and famous sayings that can fully reflect the essence of things. First of all, ask for truth and be related to the topic. Secondly, we should abandon the old arguments and use new ones. Some students memorized several classic arguments in their compositions, such as Sima Qian, Madame Curie and Zhang Haidi, and used them from different angles as a kaleidoscope. In fact, even if these arguments are typical, they are not noticeable.
