第二次直奉戰爭
Qingdao University was housed in the former Bismarck barracks that had been constructed for the German troops in 1903, i.e., during the time when Qingdao was part of the German concession in Shandong. The curriculum of Qingdao University was mainly focused on engineering and business administration and a bachelor's degree was to be awarded after four years of study. Luo Ronghuan, later a marshal of the People's Liberation Army, was among Qingdao University's students. Qingdao University fell on hard times after the Zhili clique of warlords that had ruled Shandong since the takeover from the Japanese unexpectedly lost to its rival Fengtian clique in the Second Zhili–Fengtian War of 1924. Gao Enhong was forced to resign as president of the university and funding dried up.
