Dahai has cerebral palsy, but he is not stupid. A birth accident left him with poor coordination in all four limbs and limited mobility. His parents, who spoke awkwardly, refused to give up on him and took him everywhere in search of treatment, spending nearly all their savings. Thankfully, they saved his life. From the time Dahai started kindergarten, he showed an extraordinary ability to calculate. Yet because people mocked his disability, they repeatedly looked down on him and called him stupid. He was accused of plagiarism and bullied at school. Luckily, his older brother Xingguang protected him time and again. Dahai secretly vowed that he would succeed and make everyone who had hurt him pay. By hiding his talent and working incredibly hard, he overcame all the doubts and ridicule and eventually became a scientist. When he encountered the people who had once mocked him again, he exacted his revenge on each of them. In the end, he took his parents all over the country and fulfilled his dream!
