In 1956, a couple of free-love men and women married BBB. The differences in the personalities of Wen Li (played by Jiang Wenli) and Tong Zhi (played by Zhang Guoli) have been reflected in the early days of marriage. Wen Li, who loves Soviet novels, pursues life, and has a strong petty bourgeois sentiment in her heart, is the most favored daughter in the family, and Tong Zhi, who has an upright personality and is not romantic, is also the only son of her parents. The sweet newlywed period has not yet passed, Wen Li has already added a daughter, and they are embarrassed as parents for the first time. The second daughter, Nanfang, then came to the world, and the husband and wife who were too busy to take care of themselves had to be sent to Sichuan to take care of Tong Zhi's mother. In contrast, Tong Zhi's friend Dazhuang and Dazhuang's sister-in-law are used as comparisons, highlighting the trivial joys and pains experienced together in a year's life. The emotional friction of youth, the confusion of middle-aged affairs, the hard work of elderly children, as well as the relationship between mother-in-law and daughter-in-law and the fate of the country, are all inseparable from this ordinary couple. In 2005, Wen Li had a physical health checkup, and before the results of the physical examination came out, everyone held a golden wedding celebration for the two elders, at least at this moment, everyone's hearts were stable and happy.
