Decompose from the perspective of "what is it"
That is, the central argument is decomposed from the perspective of its essential attributes.
For example, the view that "poetic life is to leave a pure land to sow ideals in countless earthly events, and then continue to struggle until life is harvested in a golden wheat field" can be decomposed into the following three sub-arguments:
Ideal is the first level: "climb the stairs alone and look at the horizon." It is the ideal that ignites the spark; Ideal washes away vast dust; It is the ideal that makes us see the end of the world at a glance and start the journey of pursuit.
(2) Struggle is the second realm: "I don't regret the widening of my belt, and I am haggard for Iraq." In Wu Fengqi, Liu Yong tells his thoughts about Iraqis, the poetry of life, and the chance to realize his ideal.
