Where does Rain Man Zhou Wei come from?

Leo Chou (199 1 year-) was born in Xiangfan Village, Donglei Township, Wutai County, Shanxi Province. When he was born for 6 months, he was diagnosed as "rickets" by the county hospital because of convulsions; At the age of two, he was diagnosed as cerebral palsy by the Provincial Children's Hospital; At the age of 3, he was diagnosed as "intractable hypoglycemia and mental retardation" by Peking Union Medical College Hospital. Many doctors and drugs can't be cured, so parents have to give up treatment and take their son home. When Leo Chou was 9 years old, the symptoms of hypoglycemia suddenly disappeared after many years, and the epilepsy did not recur. One day, Zhou Runlian took her son to work in the field. The uncle who worked together asked Leo Chou during the break: "One donkey has four legs, and how many legs do two donkeys have?" "Eight legs." Leo Chou blurted out. I didn't expect mentally retarded children to do arithmetic, and the whole family was overjoyed. Leo Chou, 10 years old, is in the first grade of primary school and studies in the same classroom as the children in the third grade. He was good at math problems in the third grade. He plays with his calculator at home every day, but he shows amazing mathematical talent. He can deduce arithmetic progression by himself, and give 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 and the fraction of cyclic decimals. Leo Chou was diagnosed with persistent hypoglycemia and mental retardation by the hospital since she was a child, but she has amazing talent for quick calculation. Known as the "Chinese Rain Man".
