Dayan Yong'an four years, Yunjin Town, Jiangnan. Su Yunjin, a 17-year-old girl from the Su family weaving workshop, faced a desperate situation when her father was framed by Zhao Jintang, the chairman of Jinxing Company, and her family's loom was destroyed by floods. She resolutely embarked on an untraveled road - to apply for the "Jinsi" established by the imperial court, a professional weaving qualification examination that no woman had ever passed.
She doesn't understand Mandarin, doesn't know a few Chinese characters, has no backer, no money, only a pair of hands and a heart that refuses to bow. Accompanied by her maid Atan, she became a disciple of the reclusive master Mrs. Cheng and learned the lost "Hidden Brocade" technique. At the same time, she unexpectedly discovered that her mother, who died young, was actually the 38th generation master of the "Shuyu Pavilion", a secret organization that has been passed down for three hundred years. Faced with obstacles from Zhao Jintang, cynicism from peers, and secret suppression from the imperial merchant Zhao family, Yunjin used hidden brocade as a weapon and grew up through setbacks. She ranked fifth in the first Jinsi examination and unfortunately failed. She was not discouraged and returned to her hometown to set up a girls' school to accumulate strength. In the second examination, she defeated the others with her painting "Feng Ming Nine Heavens" and won first place, becoming the first female Jinsi since the founding of the Dayan Dynasty.
After that, she founded a women's weaving school, teamed up with the Shuyuge sisters to expose the corruption of the Zhao family, and transformed the secret inheritance of hidden brocade into an open skill for cultivating female craftsmen. The story ends with a warm picture of her standing in front of the school door, with the sun shining brightly, which means that "the thread is continuous and the inheritance is immortal".
