Fu Zuoyi
As relations with Japan grew more tense, in February 1937, at the invitation of General Fu Zuoyi and acting under the auspices of the national YMCA, Liu formed a war zone Soldier Relief Board in Suiyuan, in western China. Liu later recalled that General Fu told him that “Mass singing and slogans are the two great weapons to train the people and soldiers. Of the two, singing is more important because during the war it can stimulate a spirit of unity among our soldiers and masses.”
