In the Great Yan Kingdom, time flows into a turbulent era. The nation is mired in a period of border wars. Barbarians from the north frequently invade the south, plundering and burning. The borderlands are ablaze, and the people are destitute. Within and beyond the imperial court, civil officials and military commanders each perform their duties, striving to maintain the functioning of this vast empire. However, a rigid social hierarchy, with the concept of male superiority and female inferiority ingrained like an iron rule, persists. Men are considered the heavens, holding power and deciding the course of events, while women are the earth, bound by the Three Obediences and Four Virtues, dependent upon their fathers, husbands, and sons, with no right to autonomy. Especially in such turbulent times, the fate of women is like floating duckweed, drifting with the tide. A single misstep could lead to irretrievable doom.
