The Du Family has a daughter, married for three months, her husband receives the emperor's order to go to war, and since then they have been together rarely and apart often.
Married for five years, her husband dies on the battlefield, wrapped in horsehide.
She cries her eyes out, adopts a clan child, and through the green lamp and old Buddha, she earns a memorial arch of chastity. This is her life's glory, and also a lifelong shackle.
In her old age, she learns that her husband's death was a conspiracy, but there is no longer anyone to avenge.
She sees the flowers filling the courtyard, just like the day he lifted her veil, and she hears cheerful laughter, reminiscent of the years he was by her side.
She knows she won't live long, standing under the memorial arch, her hand on the cold stone pillar, she doesn't want this name of chastity, she only wants him to grow old with her. She doesn't want to raise other people's children, she wants their own son.
If she could go back to the past, she would never let her husband die in vain, and would never let the enemy have a good end!
