Leo Chou is good at quick calculation. He can give fast and accurate answers to the high-power operation of natural numbers, the multiplication of two, three and four digits, the square root of high digits, the square root, the arithmetic progression, the cyclic decimal and other operations. Behind the perfect presentation of Super Brain, this talented mathematical wizard has an embarrassing growth history. According to the reporter's interview, Leo Chou was born completely healthy. When he was six months old, he was accidentally hit by a pillow and was afraid. Then his body became abnormal. His parents took him to a big city for diagnosis. Unexpectedly, he was diagnosed with intractable hypoglycemia and mental retardation. All the schools in the village refused to accept Leo Chou's smart and dull appearance, so there was no way out. Finally, Leo Chou can only become a fifth-grade auditor. 10 years old, I know arithmetic in grade one and grade three. When he finished primary school and wanted to go to middle school, he was discriminated against by his classmates at school because of his age, and finally he had to drop out of school because of the environment and people's ideas. Since then, he has been helping in the grocery store at home. Leo Chou is usually taciturn, but he especially likes books about mathematics, and he likes to do arithmetic with a calculator, so all his mathematical talents are touched and awakened during these times.

As for cultural knowledge, because Leo Chou wanted to study and was able to learn when he was a child, but no teacher was willing to correct his homework, his literacy was weak, and he was self-respecting because of frustration, and he gradually hated the special eyes of his classmates and teachers for going to school. Many people think Leo Chou is a "fool" because of his strange appearance. Doctors and experts in local small hospitals also diagnosed him as "having a verbal IQ of 49, an operational IQ of 46 and moderate mental retardation". Over the years, in order to cure his so-called "disease", my father had no choice but to seek medical treatment and almost exhausted his half-life savings. Leo Chou's father is still working in other places, and his sister has no job, so she almost sacrificed all her time to take care of her younger brother. Zhou Weijia has four brothers and sisters (28-year-old sister, 5-year-old child, 27-year-old second sister, Leo Chou and 19-year-old brother). Due to family reasons, parents can no longer afford expensive treatment fees. But for Leo Chou, his sister and mother hope that if his family is old and can no longer accompany him, he can support himself. This is the only humble hope and the simple wish of the family.
