Another reason why people are so interested in Yitang Zhang is that he had lived a tough life before his work was publicized: he was totally a little-known nobody in maths, a non-tenure lecturer at the University of New Hampshire. The documentary also focuses on Zhang's disadvantaged youth and his frustrations at his graduation. Luckily, his perseverance finally paid off. His experience is nothing but a legend.
