This paper wishes to discuss chastity as a cultural phenomenon among Han women in Taiwan from existing Taiwanese chastity epigraphy. Compared to continental areas (typically emigration origins), fewer items of epigraphy concerning woman chastity had appeared in Taiwan: this could be related to emigrant customs, to historical development, or to the bureaucracy policies of the Qing Dynasty. According to existing epigraphical evidence, Taiwanese chastity epigraphy shows a general decline in quantity, but there was an increase during the Qing Dynasty, which must have been related to the incentive policies of the Qing government. Yet the increase is still relatively minute compared to emigration origins on the continent, which implies that Taiwanese Han women have a better standard of living compared to their counterparts in their ancestral regions. During the Japanese Occupation period, chastity epigraphy was not wiped out by conflicting ideas on female chastity and virtue of the Japanese culture. Rather, the content and form of the epigraphy changed, reflecting the Japanese strategy of government that emphasized on applying existing social institutions to maintain the security and stability of social structure, to persuade social elites to accept Japanese rule.
