How did Hwang Chin-I change the subjects of sijo poetry?

In the context of Korean literature, Hwang Chin-I was instrumental in expanding the thematic scope of sijo poetry. While early sijo were primarily preoccupied with historical, political, and military subjects—often reflecting on the transition of dynasties—Hwang Chin-I, alongside Yi Mae-Ch’ang, pioneered a new realm of the genre by describing love in emotive terms.1

By shifting the focus toward personal and romantic expression, she helped move the sijo beyond its traditional emphasis on Confucian ethical values and nature, establishing a more emotive and intimate tradition within this enduring poetic form.21
