How can Wei's hand be injured and not embroidered?

Wei Yingluo's hand is frostbitten and can't embroider. Fu Cha's seventh brother started a fire because of the sparks in the charcoal basin. Wei, who later became a imperial concubine, had no charcoal basin, and her hands were frostbitten when she embroidered Buddhist scriptures for the Queen Mother. The story of Yan Xi Palace, these warm-keeping articles about the north, is what northerners can feel most. For southerners, there is only sunburn, not frostbite.
