Shen Wantang, a weaver's daughter from Suzhou, lived in seclusion in an embroidery workshop because her family had been wronged and fell into ruin. A fire destroyed her last shelter and also burned out the long-lost scroll of double-sided embroidery among her mother's belongings. She was forcibly brought into the palace. She appeared to be an embroiderer but was actually a chess piece. She was deeply involved in the overt and secret struggles in the harem.
She used needles as swords and threads as conspiracy - she discovered the poison in the embroidery thread dye, and found her father's blood letter in the interlayer of the dragon robe. Every time the needle moves, we are getting closer to the truth of the "Gongsatin Case" ten years ago. Emperor Xiao Heng initially regarded her as an informant, but he saw a different tenacity in her ability to break through the game again and again. The queen regarded her as a serious problem because the scroll of double-sided embroidery in her hand contained secrets that could subvert the harem.
When the truth came to light and the imperial decree came, she took off her phoenix crown and turned to leave: "There are three thousand people in the harem, and I am not missing one; but the embroiderers in the world need someone who can speak for them."
She established herself with her craftsmanship and convinced others with her ability, eventually becoming the first female official to take charge of the Shang Palace Bureau.
