At birth, Li Dabao was asserted by a doctor to have intellectual problems. His mother withstood the pressure of the whole family to keep him, and raised him as mentally disabled for eighteen years without needing to study, with plenty of snacks, and his life goal was just being able to eat by yourself. But he was not stupid at all, secretly working hard to rank second in his grade, entering a key high school, and university admission letters mailed to his home, stunning his whole family's jaws again and again. To clear his name, the family investigated the misdiagnosis of that year like a court trial, turning everything upside down, only to find it was just a misunderstanding of missing a return phone call. The mother's clumsy yet unreserved love never changed, just turning to a warm direction, continuing to protect him as he grew up warmly.
