Each topic is like a short essay: you must have your own thesis, then develop your supporting arguments, use apt analogies to illustrate, or cite concrete examples.
Zong (the thesis) means the central proposition—your own argument.
Yin (the reason) means the evidence, the supporting arguments, the facts.
Yu (the analogy) means a fitting and vivid analogy used to illustrate the thesis.
