Today, among the Han Taiwanese who account for about 97-98% of the total population in Taiwan Province, the majority have always been Minnan (Southern Fujian) people from Zhangzhou and Quanzhou (about 65-70%), while Hakka are in the minority. In addition, Taiwan was an “immigrant society” in the Qing Dynasty (1616 AD-1912 AD), which led to frequent “armed fights” among the ethnic groups and poor ethnic relations between Hakka and Minnan Taiwanese. In the Qing Dynasty, Hakka in Taiwan were in a weaker position than Minnan people, so they set up a “Hakka Yimin corps” to help the imperial court put down several riots led by the Minnan people. Their main purpose was to gain favor from the imperial court, who would uphold justice for Hakka in Taiwan. Although the Qing Dynasty ended, this group psychology of Hakka was still brewing in an environment with “strong Minnan people and weak Hakka.” When Luo Xianglin (罗香林) and others in Guangdong called on all Hakkas to “uphold the Central Plains” during the Republic of China, it naturally transformed into the collective psychology of Hakka in Taiwan to “uphold and cherish the Central Plains.”
