Fang Hung-chien, the hero of Fortress Besieged, is an artistic image of a senior intellectual who is looking for a spiritual home everywhere in old China. The son of a gentleman in the south of the Yangtze River, when he was studying in Peking, because he couldn't learn civil engineering, which was highly valued in his hometown, he transferred to the Department of Sociology and finally to the Department of Literature in China, and barely graduated. Due to an accidental factor (with the help of their future husbands), they embarked on the road of studying abroad unprepared. It seems a bit funny for China learners to go abroad for further study, but "in Europe, they didn't copy Dunhuang volumes, didn't visit Yongle Grand Ceremony, and couldn't find the documents of the Taiping Heavenly Kingdom ... In four years, they changed to three universities, London, Paris and Berlin; I listened to a few classes casually, and I had a wide range of interests, but I learned nothing. He has nothing but boasting. After returning home, he had to buy a fake doctorate from an Irishman in the United States under the threat of his father and father-in-law.

During my study abroad, influenced by the new trend of thought of personality liberation, I began to yearn for independent love, boldly wrote to my father to ask for the dissolution of arranged marriage, and finally I was thrown a bucket of cold water. In his flirting with Miss Bao and Sue's social intercourse, he gradually realized the difference between "girlfriend" and "lover". When he met Tang Xiaofu, a rarity of modern society, he really fell in love, but they were still in their infancy.

Fang Hung-chien and Zhao embarked on the road of seeking jobs in universities. Although San Lv University is located in a remote rural area in Hunan, it is far from a pure land. Here, there is Gao Songnian, a hypocritical and cunning bourgeois principal who keeps on defending the dignity of education; Han Yuxue, a fake foreign doctor with dull appearance and cunning heart; There are also people in politics. Liu Zixiao, a superficial and petty villain ... Fang Hung-chien, who is withdrawn and mediocre, was finally squeezed out by the intrigue of dozens of intellectuals in San Lv University and was dismissed as a teacher.

Before he woke up from the setbacks in his career, he was lured by Sun Roujia and fled to "a marriage in Sun Roujia where he was not sure whether he loved him or not", thinking that this was a happy harbor where he could escape from failure and depression and pursue a free life. Maybe Sun Roujia was too calculating before marriage. After marriage, Fang Hung-chien suddenly found himself married to someone else. The contradiction between his new home and his hometown intensified the contradiction between them. Besides, they have different personalities and are difficult to get along with. Finally, he left behind yesterday's disappointment and finally rushed out of the family siege with inexplicable hope for tomorrow.
