In Yunqi Town, a water town in the south of the Yangtze River, Mu Chenshuang (the heroine), who has been imprisoned in an attic by a feudal family since she was a child, is like a dead tree with broken branches, lingering under the curse of her father who "kills her mother." Until one day, Wen Xuchun (the male protagonist), a doctor who had returned from studying abroad, discovered that she was pushed into the cold pool by her brother. This young doctor with a Western stethoscope used a gentleness as sharp as a scalpel to cut open her soul that was corroded by feudal ethics.
When Mu Chenshuang encouraged the doctor to escape from the prison, he encountered a military disaster on his way to Wen Xuchun. Seriously injured and unconscious, she was rescued from the dead by Lu Qingyue. In the field hospital, the two scarred souls licked each other's wounds. Wen Xuchun used his body temperature to warm her frozen fingers, and Mu Chenshuang heard the most vivid heartbeat through his stethoscope.
But when peace came, the shadow of Mu Chenshuang's family shrouded again. In order to cling to the powerful, the elder brother used Wen Xuchun's safety to threaten her to marry the son of a warlord. On her wedding day, Mu Chenshuang chose to jump into the cold pool and turned her last tenderness into verses on the letter. And the field hospital built by Wen Xuchun in the war will always stay in the spring that could not wait for her.
Purpose: The confrontation between feudal shackles and the awakening of freedom: Yi Mu Chenshuang's experience of being imprisoned by her family and regarded as "unlucky" reveals the suppression and persecution of human nature by feudal ethics, shows the awakening process of women's desire to break free and pursue their self-worth under the shackles of tradition, and triggers reflection on the legacy of feudal thought.
