In the autumn of the 35th year of the Republic of China, in the fog on the border between Shanghai and the Soviet Union, Shen Lingxi, the only descendant of the Shen family's Tibetan silver embroidery in Suzhou, bore the blood feud of Burning House. Using needle and thread as a blade, he joined forces with Song Yanci, his childhood sweetheart and art student studying in France, to seek revenge. Relying on her ancestral silver caltrop needle and Tibetan silver embroidery skills, she deciphered the blood evidence of half of the broken lotus embroidery, exposed the conspiracy of Song Mingcheng, a powerful figure in the receiving office, to collaborate with the enemy and treason, clear her family's grievances, and finally rebuild the embroidery workshop, inheriting the millennium cultural heritage. In the dust of troubled times, bead buttons change from cold to warm, and embroidery colors change from bitter cold to warm. This is a story about the redemption of love and hate, the inheritance of craftsmanship, and the glimmer of home and country.
