As a fable for educating students, story appreciation tells us that bad people always try their best to find excuses to satisfy their own interests, no matter how absurd these excuses are. In the environment where the law of the jungle prevails, it is not enough to be reasonable and just, only strength can survive. Rules are always made by the strong, and history is always written by the winners. The same is true of so-called weak countries without diplomacy. In the long run, justice will surely defeat evil, but in part, strength is the key factor that determines the outcome. Strategically, we adhere to justice and firmly believe in truth; Tactically, stick to strategy and firmly believe in strength. In addition, with wonderful satirical brushwork, the cruelty and insolence of the rulers at that time were exposed.
