Fortress Besieged is the only novel written by Mr. Qian Zhongshu in 1947. Since its self-esteem edition, it has attracted the attention of literary critics. Especially since 1990s, China's study of Fortress Besieged has made great progress, and there are different opinions. However, it mainly presents three remarkable characteristics: first, the flexible use of various critical perspectives; Second, it gives a reasonable explanation for the creative defects of Fortress Besieged, or digs into the depth of research or touches the blind spot of research; Thirdly, the research on the theme implication and characters of the works is more in-depth. For example, Song Yanping's Abnormal Personality and Life in the Interchange of Chinese and Western Cultures —— Rereading Fortress Besieged and Notes on Fortress Besieged, trying to explain the theme of Fortress Besieged from three aspects: life, culture and philosophy. Compared with Midnight, the author found that Fortress Besieged handled the background differently. The deep meaning of the theme of Fortress Besieged by Royston Tan starts with the aesthetic concept of "tragic tragedy" and seeks the philosophical meaning of the theme of Fortress Besieged ... From many research papers on Fortress Besieged, it can be seen that although "the deep see its depth, the shallow see its shallowness", researchers can consciously stand at the height of the times, or trace back to culture or seek theoretical support from philosophy. As a loyal reader of Fortress Besieged, I was deeply shocked when I first read Fortress Besieged, and I was moved by it every time I reread it many times, especially the description of women's love and marriage in Fortress Besieged. Therefore, this paper discusses the love and marriage of four women in Fortress Besieged: Miss Bao, Su, Yu and Yu. For example, Miss Bao, who regards marriage as a transaction, is not only the beginning of the whole book, but also the beginning of the love life of the first protagonist Fang Hung-chien. She thinks marriage is a great event in life. This also doomed her marriage to be unhappy. Sue· A new woman imprisoned in a traditional marriage cage. From Sue's love and marriage, we see more helplessness and sadness. A talented woman, who studied abroad and learned a lot, was supposed to be the best among women. However, at the Viscount Dragon in Blaj, Fang Hung-chien chose Bao over Su, and later chose Tang, which made most people call her unfair. Later, it was a pity that she married Cao Yuanlang, a fake poet who was not only ugly but also uneducated. From the description in the book, Sue doesn't like Cao, and if she gets married because she can't get the love of Fang Hung-chien, it's even less valuable. Therefore, the marriage between Su and Yu is doomed to be unhappy. Tang Xiaofu female dream model, love perfectionist. Her expression of love is immature, and she likes Fang Hung-chien in her heart. However, if she is said a few words by others, she will hug her left and right, so we can only say that she is young and doesn't know true love. She can only be a "half woman" in Fang Hung-chien's life and a dream model in a man's heart. Sun Roujia-a young woman who regards marriage as her career. Sun Roujia is a calculating figure in the novel. Her only shortcoming is that she runs her marriage as a career, which doomed her marriage to failure. In a word, a happy marriage can only bear sweet fruit if both parties operate together. Of course, there will be a lot of hardships and sweat. If you have tasted all the ups and downs, people will gradually mature and pick their own happy fruits. I sincerely hope that female friends who have the same experience as the women in the novel can get a feeling from it and understand the meaning of "happiness".
