In the nursery of the obstetrics and gynecology hospital, two baby boys on their third day of life were "conversing" quietly. Zheng Tianbao, a baby boy with a red mole, comes from a wealthy family, while Dr. Jia (later renamed Jia Duduo), a skinny baby boy, comes from an ordinary family. A swap planned by a rogue completely rewrites their life trajectories.
Six years later, Jia Duoduo, who was supposed to be a young master from a wealthy family, grew up to be a smart, kind, precocious and tenacious young man. At the age of four, he knew 5,000 words, read through the four major classics, and at the age of three, he was proficient in mixed calculations of addition and subtraction. He was called a child prodigy by his neighbors. But his mother died unexpectedly, and his lame adoptive father cruelly kicked him out of the house. Zheng Tianbao, who was supposed to be an ordinary man, became domineering and vengeful after being pampered by a wealthy family, and became the sworn enemy of Jia Duoduo everywhere.
Just because of a woman, Zheng Tianbao's revenge on Jia Yuduo intensified, from punching, kicking, insulting and cursing when he was young, to robbing his girlfriend, stealing research results, and even hiring assassins to assassinate him as an adult. Jia Duduo relied on his mother's dying instructions that "knowledge changes everything", and with extraordinary wisdom and tenacity, he moved forward against the wind time and time again.
In the end, with the investigation of Fa Xiaoge Mufan and the intervention of the National Anti-Human Trafficking Office, the truth about the package swap came to light. Zheng Tianbao's biological father was imprisoned, and Zheng Tianbao was also sentenced on multiple charges. After his life experience is revealed, Jia Duoduo meets his biological parents in tears. Whether he forgives Zheng Tianbao, denies his ancestors and returns to his clan, and whether he keeps his promise to accompany his adoptive father to his old age, all will be revealed later in the story.
