However Taiwanese pop was soon set back. As Second Sino-Japanese War broke out in 1937, non-Japanese songs were banned, and talents were required to write songs (and change previous songs) for military propaganda. The situation worsened in 1941 when the Pacific War broke out. US bombings of Taiwan (called Formosa at the time), poverty and shortage of raw materials hit the business hard, and many talents were drafted away. This period ends with the end of World War II and handover of Taiwan to the Republic of China in 1945.
