王夫之
A popular student, in 1915 Mao was elected secretary of the Students Society. He organized the Association for Student Self-Government and led protests against school rules. Mao published his first article in "New Youth" in April 1917, instructing readers to increase their physical strength to serve the revolution. He joined the Society for the Study of Wang Fuzhi ("Chuan-shan Hsüeh-she"), a revolutionary group founded by Changsha literati who wished to emulate the philosopher Wang Fuzhi. In spring 1917, he was elected to command the students' volunteer army, set up to defend the school from marauding soldiers. Increasingly interested in the techniques of war, he took a keen interest in World War I, and also began to develop a sense of solidarity with workers. Mao undertook feats of physical endurance with Xiao Zisheng and Cai Hesen, and with other young revolutionaries they formed the Renovation of the People Study Society in April 1918 to debate Chen Duxiu's ideas. Desiring personal and societal transformation, the Society gained 70–80 members, many of whom would later join the Communist Party. Mao graduated in June 1919, ranked third in the year.
