What influence did the Sino-Japanese War and World War II have on Taiwan Province Province?

China's real effective control over Taiwan Province Province was after Zheng Chenggong entered Taiwan Province, that is, after 1662. Although Taiwan Province Province was incorporated into the territory in the Yuan and Ming Dynasties, it did not set up a government agency to manage it, nor did it immigrate to the Han nationality. Therefore, before and after the Spanish and Dutch entered Taiwan Province Province, even after the Kangxi platform, Taiwan Province Province was not vigorously developed, but only roughly managed and immigrated. Therefore, after the Sino-Japanese War of 1894-1895, the Japanese did not encounter much rebound in Taiwan Province Province, but some Han armed forces were resisting. These Han armed forces were not local, but mostly related to the mainland, such as the Black Flag Army in Liu Yongfu. When the Japanese brought advanced technology and management mode, the social level of Taiwan Province Province improved rapidly, which made the already thin sense of China even more endangered. According to the Cairo Declaration and Potsdam Proclamation, Taiwan Province Province returned to China in 1945, and the Kuomintang began to manage Taiwan Province Province. During this period, due to the serious awareness of localization, the February 28th incident against the National Government occurred. After 1949, a large number of Han ruling classes entered Taiwan Province Province, and with decades of repression by Chiang's father and son, local movements in Taiwan Province Province were suppressed.
