On the birthday of Wu Fen, who was 50 years old, her son Li Yu brought her ex-husband Li Jianguo, who had been missing for 20 years and was paralyzed by cerebral infarction, as a surprise to the banquet and forced her to take care of him. The ex-husband abandoned his wife and son back then and even fabricated millions of dollars in savings to deceive his son. Wu Fen took out the divorce agreement and had evidence of her son's 380,000 yuan investment in decoration of his new house. With the help of neighborhood committee member Zhou Zhengming, she forced her son to take her ex-husband away. After seeing her son's selfish calculations clearly, Wu Fen let go of the past, and later accompanied the gentle and transparent Zhou Zhengming, and went to Dali to open a wonton shop, and finally lived a stable and comfortable life just for herself.
