What is the main content of Cervantes' Don Quixote?

The full name of Don Quixote is La Manque's Biography of Don Quixote, which consists of two books, the first published in 1605 and the second published in 16 15.

In La Manque, a young gentleman lived in a village called Gizano. He is nearly fifty years old, tall and thin. He has a thin horse, a spear and an old shield. There is a housekeeper in her forties, a niece in her twenties and a helper at home. Generally he can live, but he is not rich. One of his hobbies is that he likes to read knight novels and is fascinated by them. He doesn't hunt and doesn't care about family affairs. Later, he even sold his land to buy such a book, and told people the truth in the book when he met people. From night to day, from day to night, he talked like this every day, so that his brain gradually dried up and he finally lost his mind. His mind is full of magic, chariots, duels, challenges, injuries, roaming, love, turmoil and all kinds of absurd things in the book. He believes everything written in the book. So I thought, in order to improve his reputation and seek public welfare, he should be a knight errant, put everything he saw in the book into practice, save suffering, experience danger and establish achievements. So he named the horse Luo Qinan Tuo, which means a horse that worked hard, found a spear and shield, imagined a country woman as his wife as a knight, went out of the village to fight bravely and traveled around the world.

In the inn, he took the shopkeeper as the owner of the fort and forced him to seal himself. Then the first injustice he encountered was that a rich farmer tortured a little shepherd boy because the shepherd boy lost his sheep while herding them. Don Quixote was not satisfied. He not only asked the rich peasants to release the shepherd boy, but also asked the rich peasants to pay the nine-month salary he owed the shepherd boy. The rich man's name is Hao Tuduo. Although he promised to come down at that time, when Don Quixote left, he tied up the little shepherd boy Andreas and beat him up, but his righteousness was fruitless. Later, he returned home, made an appointment with his neighbor, an honest farmer, Sancho Bossa, invited him to be a squire, and promised to call him the governor of the island in the future. So Sancho, with a dream, rode on a donkey and went with him as a servant to "make contributions". In the two adventures of a ranger, I played countless jokes, such as treating windmills as giants, hotels as castles, exiles as persecuted knights, skins as giants' heads and so on. Finally, Sancho locked him in a cage and pulled him back with an ox cart.

But he was still stubborn and started his third ranger after his injury. Sancho really became the "governor" this time. Don Quixote couldn't wait for Sancho to implement the plan to transform society, but he was teased by the duke and his wife and almost died. Finally, he was defeated by Baiyue Knight disguised as a bachelor of Galapagos in the same village and was forced to return to his hometown, and he was bedridden from then on. Finally, when I lay dying, I woke up rationally and found out the absurdity of my past. I made three wills before I died. First, I used to pay Sancho a sum of money, so I don't have to forget it. I spent the rest of my money on him because he is kind and loyal. Second, all the inheritance belongs to the niece, but if that person wants to read knight literature when he gets married, he should not marry such a person, and all the inheritance should be recovered and allocated to religion as publicity expenses; The third is to apologize to the author of this absurd book, who has a conscience burden for it. Finally, the knight died peacefully.
