In Spring of the Blade (一瓯春), viewers learn fast to hiss at Madam Hu (扈). She poisons rooms with a smile, and the camera agrees she is bad. But the deeper fear arrives later, quietly, when Old Madam Xie lifts her Buddhist prayer beads. She nods at bows. She thanks servants for tea. People call it dignity. Rewind, and every calm frame hides a death. Her granddaughter? No—her true daughter is Jin Chunqing (靳春晴). The child she raised as a son is Xie Shu (谢纾). Xie Qingyuan (谢清圆) returns to Xie Manor hunting revenge, but the trail ends not at a knife. It ends at a ledger kept under smooth beads. She never raises her voice; the house obeys her pauses. The worst killer in this story may be the woman everyone calls merciful.
The First Swap
Old Madam Xie did not begin as a monster with a mask. She began as a woman in a chair too new for her. A daughter could not secure that chair. So she traded her baby girl for a boy from outside. The boy became Xie Shu. The girl became Jin Chunqing, raised in an opera troupe, fed on hunger and other people’s songs. Within the same walls, years later, Jin Chunqing returned as a concubine. She slept beside the swapped son. She gave him a daughter, Xie Qingyuan. Old Madam Xie watched. She said nothing. Silence was not ignorance. It was policy. A mother can recognize her own child’s hands. She chose not to. The first crime was not murder. It was a signature on an unwritten contract: family face first, blood second. The swap was not a wild act. It was careful housekeeping. A girl was removed like a stain.
That contract explains the next silence. When Concubine Xia (夏) died and the blame slid onto Jin Chunqing, Old Madam Xie did not ask for proof. She ordered Jin Chunqing out of Xie Manor. The woman was pregnant. The old lady had the keys, the servants, the years. She could have torn the lie apart. She did not want the truth on the table. A scandal in the back courtyard would stain the main hall. An exile would end the noise. So she signed again. Her daughter left through the same gate twice: once as a traded baby, once as a blamed woman. Old Madam Xie never blinked. In her ledger, Jin Chunqing was not a daughter. She was a cost. Servants could whisper. Neighbors could guess. The gate could close. That was enough.
If the story stopped there, she might still be called cold. It does not stop. Xie Shu learned the truth: Jin Chunqing was the real Xie blood. He did not kneel or ask forgiveness. He rode through the night, killed the woman he had called wife, and set the house on fire. Xie Qingyuan was a child. Shen Run (沈润) covered her mouth in a corner. She watched her father kill her mother. She watched flames eat the room. When Old Madam Xie heard, she broke down. Many viewers read that as conscience. It was not. She wept because her fake son had murdered her real daughter. The family name was now in danger. Her first thought was not “my child is dead.” It was “how will the Xie family face anyone?” The fire burned evidence, but it also burned her plan. For once, the ledger shook in her hand.
The Last Ledger
That tear did not change the account. It only added fear. Old Madam Xie kept calling Xie Shu her son for more than ten years. She needed him at the table, in the hall, in front of guests. A missing heir would ask questions. A murderer in the family would break the mirror she had polished for decades. So she smiled at the man who killed her daughter. She let him pour her tea. She let him bow. The beads clicked in her hand, smooth as river stones. Each click said the same thing: keep the house standing. Keep the story clean. Keep the dead buried. The living could be managed. The dead could be forgotten. That was the ledger she chose to read every morning. No one at the table knew what her smile cost. She paid with the only coin she had left: her daughter’s name.
Xie Qingyuan returned to Xie Manor with revenge in her mouth. She followed clues through servants’ gossip, old papers, and frightened eyes. At the end, she found two monsters. One was Xie Shu, a father with blood on his hands. The other was Old Madam Xie, a grandmother with clean sleeves and a colder math. Xie Shu’s evil was a blade. Hers was the hand that made the blade necessary, then hidden, then respectable. She swapped a daughter to build power. She exiled a daughter to protect power. She mourned a daughter only when power trembled. Every choice taught the family one lesson: shame matters more than people. Once that lesson entered the walls, every later cruelty became possible. The house did not need a devil. It needed a manager. She was excellent at the job.
The prayer beads never stopped moving. They grew warm and glossy from touch, but they never softened her arithmetic. In her book, kinship had no column. Only reputation did. That is why the final answer to the question in the title is not Xie Shu alone. He killed Jin Chunqing. Old Madam Xie created the conditions for that killing, then protected the killer. The tragedy of three generations did not start with fire. It started with a mother handing her baby away and calling it strategy. When Xie Qingyuan finally reaches the deepest truth, she does not just face a vicious father. She faces the quiet author of the whole ruin: Old Madam Xie, merciful on her lips, murderous in her sums. The beads are not a sign of grace. They are a cover for bookkeeping. Her mercy is a locked door.
