The story takes place in South Korea in the 1960s. Xu Sanguan (played by Ha Zhengyu), a poor young man living in a village, fell in love with Xu Yulan (played by Ha Jiyuan), the most beautiful girl in the same village. It is rumored that Yulan is the girlfriend of the gangster He Xiaoyong, but Sanguan persuaded his future father-in-law with his perseverance and shameless spirit, and got the beauty as he wished. After a few years of marriage, the couple gave birth to three clever and naughty sons, Yile, Erle and Sanle, and the family's life was also enjoyable. But Yile looked more and more like He Xiaoyong, which attracted a lot of discussion from the villagers, which made Xu Sanguan restless, and his feelings for Yulan and Yile seemed to have changed. In that era when selling blood was popular, Sanguan once exchanged his blood for money. What he didn't expect was that in the rest of his life, he would have to sell blood again and again for his family, pale and weak, and his life was at stake... This film is adapted from Yu Hua's novel "Xu Sanguan Selling Blood".
