A Doll's House is one of Ibsen's representative works of social problem drama. Also translated as "Nora" or "Puppet Family". The heroine Nora forged her father's signature to borrow money from others in order to treat her husband Helmer's illness. After Helmer found out the whole story, he was worried that it would affect his reputation and status, so he lost his temper with her and even wanted to deprive her of the right to educate her children. When the creditor was inspired to return the IOU, he immediately smiled at his wife. But Nora has awakened and realized her husband's selfishness and the inequality between husband and wife. She is just a doll of her husband and runs away angrily. Through the process of Nora's awakening, the play profoundly exposes the hypocrisy and irrationality of laws, religion, morality, marriage, etc. in bourgeois society, and raises the issue of women's liberation. Although she did not give a clear answer, Nora's move to run away played a positive role in the women's liberation movement at that time. In terms of art, the script closely revolves around "forged signatures", with intense conflicts and intense contagion.
