Ibsen is a master of realistic drama, famous for his social drama and known as "the father of modern European drama". Facing the society and reality is the greatest feature of his plays. Written in 1879, A Doll's House describes the self-awakening process of the heroine Nora from trusting her husband to breaking up with her husband and finally leaving the Doll's House, which profoundly exposes the ugliness of capitalist society and enthusiastically praises women's liberation. The work reveals social contradictions from the contradictions between husband and wife in the family, and the different personalities of Nora and Haier Mao are vividly reflected in the work. Nora is a female image with bourgeois democratic thoughts. She was born in a middle and small bourgeois family, and her father was not rich. "As soon as I got the money, it somehow leaked through my fingers." According to Haier Mao, Nora's father is an "unbelieving, immoral and irresponsible" person. In fact, he is a down-to-earth person who is busy making a living. This family environment undoubtedly has a certain influence on Nora's growth. Nora was educated by a bourgeois school. She was good at singing and dancing, and she was naive. She is easily satisfied with her happy life in Xiaotian and has many unrealistic fantasies. She is different from the big bourgeois women and ladies, who pursue a meaningless decadent life. She doesn't want to live a parasitic life. In order to support her family, she knitted, embroidered and copied. Although she is sometimes "very tired", she is "very happy". Nora's tireless work, optimism, contentment and love of life are closely related to her family background. She sympathizes with the victims and unfortunate people in society. Nora extended her hand of friendship and expressed deep sympathy for Dr. Ruanke's misfortune. Nora's more valuable quality is stubbornness and refusal to yield to evil forces. On the outside, people think that she is a carefree person, but in fact this is a misunderstanding. She said to Mrs. Dānlín, "Do you all think that I haven't experienced any troubles in this troubled world?" Actually, it's not like this. She also has "troubles", such as family financial difficulties, borrowing money to treat her husband, and trying to pay off her debts after borrowing money, but she never becomes dejected and despondent. Still very positive and optimistic. Crookes, the creditor, threatened her with the fake signature on her IOU, and she showed no weakness. In order to save her husband's life, she went to borrow money, and the creditor bullied her. She is still tight-lipped, and she is firmly prepared to take all the responsibilities. To save her husband's reputation, she even decided to commit suicide. These are all manifestations of Nora's stubborn character. Nora's unyielding spirit is the character basis of her final break with Haier Mao and her separation from the "doll house". If you are a weak woman, even if you know her husband's bad qualities, it is often impossible to take the action of disowning her husband. Nora resolutely broke up with Haier Mao, and more importantly, she had her ideological foundation. Real life has educated her, making her not only recognize Haier Mao's ugly soul, but also realize the irrationality of the real society. Nora's views on education, morality, religion and law in capitalist society are different from those of ordinary bourgeois mediocrities such as Haier Mao. Nora after "awakening" is hostile to capitalist society. When Haier Mao said that she "you don't know our society", she replied emotionally: "Is society right or me right!" "I know most people agree with you, and that's what the book says. But from now on, I can't believe what most people say, and I can't just believe what is in books. " Nora will not take religion, the spiritual opium that paralyzes the people, seriously. She declared, "I really don't know what religion is." Nora was tortured by the laws of capitalist society, and she hated them even more. "The laws in this country are different from what I thought .. I don't believe there are such unreasonable laws in the world." Nora's words show that she is a woman with democratic ideas. Although Nora is not a perfect person, her separation from Helmut is the inevitable result of her struggle against democratic ideas. By portraying Nora as a vivid female image, the author expresses the ideological desire of middle and small bourgeois women to be free and independent and to safeguard their personal dignity, and expresses some doubts, negations and criticisms on the existing capitalist system. Ibsen criticized the hypocrisy of marriage and family, the irrationality of ethics and law and religion in capitalist society through the negative image of Haier Mao, and exposed the ugliness of the bourgeoisie. There is a famous saying in his play "Pillars of Society": "Moral shirts have a musty smell-like a shroud worn by the dead." Women have always been oppressed. In feudal society, they were slaves of their husbands and suffered all kinds of abuse. In capitalist society, women have not been truly liberated. As tools for husbands to enjoy themselves, they still have no free and independent personality. Women are opposed to being dolls and want to be free and independent. In capitalist society, this is an extremely common and serious social problem. Floating away, just to "save yourself." The profound significance of A Doll's House goes far beyond the exposure and criticism of an individual bourgeois mediocrity like Haier Mao, which greatly scares the defenders of capitalist society. They thought Nora's departure was a serious violation of the law and made a vicious personal attack on Ibsen. They abused Ibsen for destroying the "good family order" in Europe, and he was a morally corrupt writer, demanding that A Doll's House be banned. In this case, Ibsen angrily wrote another social drama "Ghost", which strongly refuted the shameless slander of bourgeois society through the process that Mrs. Alvin reduced to old ethics and sacrificed old ideas. Therefore, from here we can see more clearly how powerful the social effect of Ibsen's A Doll's House is, and how sharp and profound the social problems he raised in the play are. Nora's departure is of great historical significance. But under the specific social and historical conditions at that time, it was impossible for her to achieve real success in this action. Due to the limitation of class, society and environment, Ibsen can't and can't draw a correct conclusion about their life problems and find the right way for the complete liberation of women. "Because of the underdeveloped social life in Norway, we can't escape from the illiberal and dark society that created the doll house. As Mr. Lu Xun said: "Nora's speculation really has only two paths: not depravity." In the process of showing life and revealing the fate of characters, Ibsen can deeply penetrate the life problems he thinks into the hearts of the audience or readers with heartfelt strength, so that people can chew the meaning in the aftertaste and think and explore these problems.
