After the establishment of the central argument, the development of argumentation ideas often involves the decomposition of the central argument, that is, the establishment of sub-arguments, which can often be established by the following methods:

Parallel decomposition

1. method-how to do it is to answer the question of how to solve the central argument or theme, that is, to refine the sub-arguments from the aspects of solutions and ways.

2. Category-what is it, that is, what constitutes the central argument or theme of the answer, that is, the sub-arguments are extracted from the categories and nature of the answer. If you are loyal to discipline, you can achieve: (1) Loyalty is the magic weapon of self-motivation; (2) Record Festival is the pillar of the Chinese nation standing proudly in the world; (3) The scale is a steelyard to measure people's moral character.

3. Because-why, that is, what is the reason for answering the central argument or topic, that is, refining the sub-arguments from the reasons and purposes of answering. That is, take the central argument as a conclusion to trace the conditions and reasons for this conclusion. For example, learning tolerance: (1) Because tolerance is a virtue and a traditional virtue of the Chinese nation; (2) Because tolerance is a good way to get rid of jealousy; (3) Because tolerance not only encourages others, but also gains something for yourself (you will get more help if your interpersonal relationship is harmonious).

4. What happens if you answer the central argument or topic, that is, what is the meaning and effect, that is, refine the sub-arguments from the aspects of the answer results and effects (meaning, function, value and influence). If you seize today: (1) If you seize today, you seize the time; (2) To seize today is to seize hope; (3) Grasping today means grasping success.

(2) Progressive decomposition

1. Doubt method. That is to say, according to the questioning idea of "what-why-how", the argument is refined. Such as argument: life should be colorful.

(1) A colorful life means that life should not be a pattern. (What is it? )

(2) Conforming to human nature (people have various spiritual needs); Conducive to people's all-round development and physical and mental health; It is conducive to fully mobilizing people's enthusiasm and forming a lively situation. (why)

(3) Be able to combine work and rest and cultivate various interests in life; Society should create conditions for people's all-round development. (How is it going?)

2. Analyze the arguments in the order of meaning from shallow to deep.
