Gao Yonghan is an 8-year-old boy and, just like any other boy his age, he likes to play. But unlike other boys his age he has another interest — solving Mathematical Olympiad puzzles. Because Gao Yonghan has an IQ of 146. At the age of 8, he is already learning all the subjects of junior high by himself at home. Both his school and his parents are having trouble keeping up with him.

According to Gao’s mother Gao Xin, Yonghan could not even speak at the age of 2. She took him to the hospital but the doctor did not find anything problematic. One day, when Yonghan’s grandmother was carrying him upstairs, she counted “one, two, three, four, five” as she took each step and, surprisingly, Yonghan suddenly followed with “six, seven, eight, nine.” At the age of 3, he was doing Sudoku and was able to recite the times table. After he turned 5, he could solve Mathematical Olympiad questions of the first and second grade.

Now Yonghan takes three afternoons a week to study at home. His teacher said Yonghan was the cleverest child she had ever seen in her 20 years of teaching. Though now Yonghan is in the first grade, he is already able to study courses of the junior high, and his ways of solving mathematical questions are unique and efficient, according to the teacher.

Yonghan says his dream is to be a mathematician. For him, studying is a thing of great fun. However, Yonghan’s parents are now bewildered about how to educate and raise him in the future since he is such an exceptional child.
