The Story of Cao E

At a Glance

• Central figures: Cao E, a fourteen-year-old girl from Zhejiang; and her father, a shaman who drowned in the Shun River during a ritual to the River God.
• Setting: Eastern Han Dynasty (25-220 AD), Zhejiang province, along the Shun River.
• The turn: After seventeen days of failed searches for her father’s body, Cao E threw herself into the river where he had drowned.
• The outcome: Five days later, both bodies washed ashore together. The villagers built a temple in her honor, and the Shun River was renamed the Cao’e River.
• The legacy: The Cao E Temple was built where she lived, and the Shun River was renamed the Cao’e River in her memory - both enduring as sites of remembrance for her act of devotion.

Her father worked the river’s edge for a living. He was a shaman, and every year he performed the rituals that honored the River God, wading in close, reading the current, calling on forces older than the dynasty. The Shun River did not distinguish between a holy man and any other man. During one such ceremony, the water took him. The current swept his body away, and the villagers who searched for him found nothing.

His daughter Cao E was fourteen years old.

The Shaman and the River God

Cao E’s father had served the River God for years. His rituals were the kind that required proximity - not prayer at a safe distance, but standing near the water’s edge when the currents ran strong, when the annual ceremony demanded it. He knew the river. That knowing was not enough.

When he drowned, his body did not return to shore. The Shun River kept him. In Confucian practice, the obligation of children toward their parents did not end at death - it required proper burial, proper rites, the body committed to the earth with ceremony. Without a body, none of that could happen. Cao E understood this. She had grown up understanding it.

Seventeen Days

The searches continued for seventeen days. Villagers went into the water, walked the banks, watched the places where the current slowed and things surfaced. They found nothing.

Cao E mourned at the river’s edge. She did not stop coming back. Day after day she returned, calling her father’s name across the water. In some accounts the weeping lasted without pause; in others she simply stood and watched. Either way, seventeen days passed, and the river gave nothing back.

She made her decision.

The Daughter Enters the Water

On the seventeenth day, Cao E walked into the Shun River. She did not go in to swim, or to search by hand along the riverbed. She went in to find her father, whatever that required - to retrieve his body, or to follow him. She was fourteen.

Five days later, the river returned both of them. Cao E’s body and her father’s body came to shore together, found by the same villagers who had failed to find him in seventeen days of searching. The two were brought out of the water side by side.

The villagers gave Cao E a funeral. They told the story to their neighbors, and the neighbors told it beyond the province.

The Temple and the Renamed River

The region honored her in ways that outlasted the dynasty. A temple was raised in her name - the Cao E Temple - and families came to it with prayers, especially prayers concerning family relations, the obligations of children to parents, the matters that Cao E had taken to their extreme conclusion. The temple stood not as a monument to grief but as a place where the living could address what she had embodied.

The river itself was renamed. The Shun River became the Cao’e River - her name folded into the geography, made permanent in the way a river name is permanent, spoken every time someone asked where the water ran or how far the boats could go. Her story entered poems and folk songs and dramatic performances. She became a figure against whom the devotion of daughters was measured - not as a burden placed on young girls, but as an account of what filial piety, xiao (孝), looked like at its most absolute.

What the River Kept and What It Gave Back

Xiao is the Confucian term for the care and reverence that children owe their parents - not merely affection, but a structured obligation, maintained through a parent’s life and extended beyond death through proper burial and remembrance. Cao E’s story lived in this tradition not because it was typical, but because it was extreme. No one expected a daughter to drown herself retrieving her father’s body. The point was that she did not weigh the cost.

Her father’s ritual work had brought him close to the river every year. It was the same proximity that killed him. Cao E did not keep her distance from that danger - she walked into it, accepting the same terms the river had offered her father. Whether the villagers read this as courage, or grief, or the logic of filial duty taken to its end, the story did not parse the distinction. She went in. They came out together.

The Cao’e River still runs through Zhejiang. The temple still stands. What the water took, and what it returned, is remembered in both.
