The plot of the novel is based on the experiences and experiences of people such as Pickwick on the journey. Although some stories are relatively independent, the progress of the stories can naturally connect, which is just suitable for publication in the form of installment serialization. There are coachmen, poor students, servants, hooligans, warders, landlords, priests, gentlemen, lawyers, chief writers, politicians, judges, etc., almost depicting people of different classes in society at that time.

There are generally four clues in the plot of The Legend of Pickwick: the landlord, Mrs. Bader, sued Pickwick for breaking the engagement; The dispute between Sam Wheeler's father and the hypocritical priest Sturgins who cheated to eat and drink; Love stories of several members of the club; The conflict between Pickwick and Sam Wheeler's servant and rogue Gingell. The book runs through with the last clue. Influenced by Pickwick's morality, Gingell finally turned over a new leaf and vividly preached the moral creed that good triumphs over evil.

Although Pickwick is an old gentleman, he is ignorant of the world, keen and helpful, which is a typical example of his kindness and fraternity. Pickwick was caught in multiple embarrassing situations during his trip, and his works tried to render his innocence, naivety and ignorance of life, hitting a wall everywhere. Pickwick is always kind enough to do stupid things, making a fool of himself everywhere, and maintaining an optimistic and cheerful personality despite repeated setbacks, which makes people feel ridiculous and cute. Objectively speaking, he has the character of a nobody and is the embodiment of the common people.

Sam Wheeler, Pickwick's servant, plays an important role in the book. He was born in a poor family, and he was mixed with the lower class people in the city. The social university hall made him know the world and helped his master out again and again, which fully showed his resourcefulness, courage and ability. Their master and servant are a fool and a wise man, which set each other off and become interesting. They not only add a lot of jokes, but more importantly, make their works more artistic.

Anyone who is related to the law in the novel is either bought by money or a criminal. Pickwick was inexplicably sued by his landlord, Mrs. Bader, who wanted to marry him. Pickwick was imprisoned for refusing to pay compensation, and the lawyer took Mrs. Bader to prison because she could not get remuneration from the compensation. This is really a ridiculous trial. The depiction of scenes and characters in a dark prison makes people feel that it is simply a hell on earth. These absurd plots are extreme sarcasm and ridicule to the courts and prisons. The book also vividly depicts the ridiculous election scene in the town of Izzy. Two rival parties in the town attacked each other when they were running for Congress, which made the residents in the town crazy with excitement. As a result, dizziness prevailed among voters, and many people lay unconscious on the sidewalk. The ugliness and caricature of the bourgeois two-party system and democratic elections was the most pungent mockery of the British political system at that time.

With distinct love and hate, the author successfully created characters with different personalities by using fascinating storytelling skills and wonderful comedy techniques. The author not only paints the positive characters with a comic color, but also uses comic artistic means to exaggerate and caricature the negative characters and ugly phenomena, making people see that they are contemptible and ridiculous, achieving the artistic effect of sharp ridicule and angry condemnation.
