On the 19th day of the twelfth lunar month, heavy snow closed the door. Shen Qiuhe opened his eyes and injured his left leg after falling. Only his blind grandmother and five-year-old brother were left at home. Li Zheng, Shen Demao, held an IOU, forcing her to pay back four taels of silver before spring, otherwise she would take back three acres of thin farmland. All the belongings in the family - seventeen cents and a rusty sickle. In the wind and snow, she thought of a herb that only grows in the twelfth lunar month - snow primrose. Climb the cliff, pick red ears, and sell them to the drug store. This is just the first step. When Shen Qiuhe walked back to Liugou carrying a basket of herbs, she didn't know that heavier snow was still to come. Hoarding grain, clearing wasteland, fighting for justice, and building workshops, a lame girl needs to gain a foothold in Qinghe County, relying not on strength but on brains.
