Xiao Tiancai, a mountain girl orphaned since childhood, depended on her grandmother. Her grandmother left her a jade bracelet and instructed her to study and leave the mountains. After her grandmother passed away, her uncle and aunt seized the jade bracelet, mistreated her, and even wanted to sell her, but fortunately, a teacher collected evidence and protected her education. She studied hard, became the top provincial scholar, and was admitted to Jinghua University. Facing the clinging relatives, she drew a clear line in public. After graduation, she returned to her hometown to teach and sponsor left-behind girls, living up to her grandmother's expectations.
