How did the hero of Maishou agree to shoot?

The director insisted on persuasion. "Wheat Harvest" is a documentary directed by Xu Tong, which was released at the Beijing Independent Film Forum in 2008. Because the director persistently persuaded the protagonist to go home, he was finally moved by the director's true feelings and agreed to shoot. The film records a rural girl's two living conditions before and after the wheat harvest between Beijing and the countryside.
