What kind of social phenomenon does the story in the fable poem expose and attack?

Allegory poems first exposed and criticized the dark corruption of feudal dynasties and their ruling institutions. In The Beast Suffering from the Plague, there is a realistic painting of the imperial court. The hypocrisy of the lion king, the overbearing and insidious ministers, and the innocence of the king, all of which are vivid. At the beginning of the poem, the epidemic plague among animals was described, which caused them great panic, so the lion king held a meeting to ask for advice. It said that this disaster was caused by God "because of our sins", and only by "offering the most sinful sacrifice among us to the angry God can everyone be cured". The fox immediately flattered the lion and said, "Your Majesty is careful and meticulous ..." This sentence won a full house applause. For the heinous crimes of big beasts, other beasts "don't dare to offend". The donkey himself admitted that he had chewed a piece of grass as big as his tongue, and was said, "It's a terrible crime, and it deserves to die!" The result was flooded. The funeral of the dead lion depicts courtiers as "a group of color-changing lizards", "bumblebees and bees" and other articles sharply accuse the court of hurting people. The judge is like a vicious Elvis Presley. In this realistic picture depicted in fable poems, there are also attacks on feudal dignitaries and monks, the pillars of the system. Wolf and Sheep reveals the jackal logic of "might is right" through the vivid and dramatic dialogue between Wolf and Sheep. Wolf swallowing sheep is an image portrayal of the aristocratic class absorbing the essence from the people in real life. "Heifer, Goat, Sheep and Lion Partner" describes that the lion seized all its prey by force, and wrote about the arrogant plunder of the people by feudal dignitaries. In the poem, the lion shared its prey with its partner and said, "The first one should be mine, because my name is lion, which is indisputable. The second copy, in terms of rights, should also belong to me; This right, you know, is power. I am the bravest, so I want the third one. If any of you touches the fourth copy, I will strangle him at once. " The poem also reveals the parasitism and decay of nobles, comparing them to busts (foxes and busts) with beautiful heads but no brains; "Only clothes are all their talents" (monkeys and leopards); Condemning the nobles for hunting and entertainment in farmland, "making the king suffer" (Gardener and Noble). Chicken, Chicken, Cat and Mouse exposes a hypocritical monk who wears a religious cloak and does evil. In fable poems, the content reflecting the miserable life of working people occupies an important position. The Death Woodman describes that farmers are "exhausted and miserable" and "have they ever enjoyed happiness" under the burden of tax debts, war corvee and heavy family pressure all the year round. Shoemakers and bankers point out from another angle that what the poor want is not "what people think they work hard for"-money. The woodcutter and messenger also praised the valuable quality of the woodcutter who is not greedy for money. It is in these workers who live at the bottom of society that the author sees their virtue of honesty and diligence. Fable poems collect many proverbs or lessons from people's lives and struggles. Lafontaine attaches great importance to these maxims and lessons, and thinks that the soul of fable poetry lies in them. For example: "Charity is good; But to whom? This is the problem (country people and snakes). " Because people have to keep fighting. Peace itself is excellent, I agree; But what's the use of peace when you meet an untrustworthy enemy? "("Wolf and Sheep ")" Work hard; Labor is the most reliable wealth. "
