After her mother suddenly passes away and her father remarries, her mother's jewelry and personal belongings become coveted, and her room is taken over. Family ties repeatedly give way to material interests. Rather than drowning in grief, she takes up the metalworking skills her mother left behind, using a hammer and file as her armor. While keeping up with her studies, she hones her craft in the narrow spaces left to her, fighting against schemes and dispossession. From copper-wire hairpins worth just a few yuan to the renowned Guihe Rice Ear collection, Shen Zhihe relies on no protection from blood ties. With a craftsman's dedication, she chisels out a promising path of her own.
