During the reign of Emperor Wen of Han Dynasty, there was a Chunyu Kun in Linzi County, who worked as Qi Taicang Order (managing Beijing granary). After resigning to practice medicine, he helped the poor and won popular support. But because he knew the truth and told the truth, he offended the powerful and sentenced him to "corporal punishment." He has five daughters, and the youngest daughter, Ti Ying, is the most beloved. He gave boys the same education and made them understand that there was a stubborn force to face difficulties. A neighbor's teacher accidentally hurt a student's hand and offended the royal family. Shi was encouraged to learn from the teacher, but he was known as a dutiful son and was called to Beijing. In contrast, Chunyuyi feels wronged but no one can sue. In prison, he lamented that "five women are worthless". Unexpectedly, it was his youngest daughter, Ti Ying, who bravely wrote to Emperor Wendi, which not only leveled the unjust prison, but also urged Emperor Wendi to abolish corporal punishment. An underage girl can do things that ordinary people dare not do and can't do. Even the emperor and empress were deeply moved: Chunyu Kun's "teaching a daughter like a godson" is actually a kind of melon!
