Apart from studying Japanese and Chinese, he also likes to play acrobatics on the trampoline in the backyard, take a big roof, and even dart, play the piano and play table tennis with visitors. When asked Graham, what motivated him to master the skills of one after another, he would say that he wants to keep his brain sensitive in order to solve the thorny mathematical problems. In his opinion, the more you use your brain, the better it works; the more you exercise a variety of intelligent exercises, the more likely you are to be associated with scientific discoveries
