Qin Guixiang worked as a skilled cotton beater at her older cousin's quilt shop for many years, but a wedding quilt stuffed with old cotton nearly made her take the blame for someone else's wrongdoing. Carrying her cotton-beating bow, she walked away and started from scratch in a borrowed warehouse. She insisted that every batch of cotton be weighed upon arrival and departure, registered with a number, and marked with her own identifying stitches. Facing low-price competition, counterfeit fabric labels, and forty defective quilts, she used secret red-thread codes, account books, and delivery records to uncover the truth. She saved an order for one hundred quilts, regained her customers' trust, and ensured that every female worker received recognition for her labor. Years later, she sewed the old plum-blossom knot left by her grandmother into her daughter's wedding dowry, allowing an old quilt to carry the warmth and dignity of three generations.
