Abstract of Xu Deheng's article "60th Anniversary of the May 4th Movement": On May 3rd (Saturday), a general meeting of all students was held in the auditorium of Peking University Law Department (later the Third Hospital of Peking University). About 13 students from Beijing technical secondary schools and above attended, including all students from Peking University, Tsinghua Normal University, CUHK, Chaoyang Law School, industrial specialized schools, agricultural specialized schools, legal specialized schools and medical specialized schools. The people attending the meeting were very enthusiastic. Liao, a senior law student at Peking University, was presumed to be the temporary chairman, while Huang Rikui and Meng Shouchun, liberal arts students at Peking University, were presumed to take notes and promote the drafting of the declaration. The speakers are Zhao Qing, Xie, Zhang, Xia Xiufeng, student representatives from all schools. There are four measures to be solved by the conference: (1) unite all walks of life and make concerted efforts with Qi Xin; (2) Electrify the Paris envoy and insist on not signing a peace treaty; (3) Electrify all provinces and cities across the country to hold mass demonstrations on the National Shame Memorial Day on May 7; (4) A large-scale academic demonstration will be held in Tiananmen Square on May 4th (Sunday). When the meeting was very tense, Liu Renjing, a classmate aged 18 or 19, took out a kitchen knife and tried to commit suicide on the spot to inspire the people of China. Xie, a law student, was heartbroken and filled with indignation. On the spot, he bit his middle finger, tore off his skirt, and bloodily revealed the words "Give me back Qingdao", which aroused the emotions of all the students, so he decided to hold a demonstration the next morning, May 4. Everyone applauds and agrees. Get ready for action. That night, the students in Xizhai stayed up all night, making flags with bamboo poles, making long flags and short ones. After the declaration was written, I tore my white sheets into banners and wrote slogans until dawn. Some students bit their fingers and wrote slogans on bloody books. At that time, there was no slogan "Down with imperialism". The main purpose of the rally is to recover Shandong's sovereignty, Qingdao, resist Japan, oppose foreign powers and punish traitors and warlords and bureaucrats. Slogans are: "Recover Shandong power", "Punish traitors", "Refuse to sign at the Paris Peace Conference", "Resist powerful foreign forces" and "China is China of China".
