 The first job of the Preparatory Committee was to plan a protest to against the "April 20 Incident" because the government distorted the truth of the incident and covered up the fact that the police beat students.The student protest against the "April 20 Incident" organized by the Preparatory Committee, however, was unorganized as the committee members lacked experience.Due to the failure of the "April 20 Incident" protest, there was a need to improve and reorganize the Preparatory Committee in Peking University.
