Jiao Yulu was a model cadre in the 1960s. The person next to him seems to be Chen Yonggui, the leader of the Dazhai production brigade and a model in his own right. This impression is strengthened by the booklet in "Chen's" hand: 愚公移山 (Yu gong Yishan, The foolish old man who moved mountains), the parable with which Dazhai was compared and one of the "Three Constantly Read Articles".
