The old windcoat from Fuxiu Weaving Workshop is not torn, yet its unbalanced shoulder and back, inner-layer, and hem structures cause it to constantly sway off course in strong crosswinds at high altitudes. Bian Suxiang refuses to blindly replace the materials. Instead, she and her companions investigate the causes by examining the old garment, selecting new threads, and adjusting its airflow-guiding structure, making repeated corrections through multiple field tests. The new windcoat ultimately reduces the burden on those who wear it, while teaching everyone that true craftsmanship is not about blindly clinging to tradition, but about respecting facts, daring to experiment, and knowing how to cooperate. With responsibility and patience, experience can be transformed into more reliable solutions.
