19 15 Zhang was admitted to the preparatory course of university law school with excellent results. However, due to the long academic system of Shi Jing University, it is estimated that his economic conditions are difficult to support, so he did not go to Peking University. During this period, he learned that the tuition fee of Beiyang University was cheap, and the preparatory class lasted for half a year, so he excitedly took his friends to enroll in the law preparatory course of Beiyang University. With excellent results, Zhang became attached to Beiyang and stayed for five years. Feng Hailong said that under the training of Beiyang University, Zhang's thoughts have been sublimated, from a patriotic youth to a producer. On the eve of the May 4th Movement, Zhang, who was studying at Beiyang University, came into contact with Marxism-Leninism. The May 4th Movement aroused the enthusiasm of young people in China. Zhang took an active part in the revolutionary movement, constantly explored revolutionary theory, and gradually became one of the founders of China * * * Production Party.
According to Yi Shi Daily, during the May 4th Movement, Beiyang University students went on strike and organized 44 lecture groups to protest against the authorities' suppression of the student movement. The second batch of four speakers, including Zhang, went to Tanggu to give a speech. At this time, Zhang completely abandoned the traditional concept that studying is for career and stable life, and abandoned his family and career for faith, country and people.
