Meng Lian and Meng Chen lost their mother at a young age, and their father was foolish, so the heavy responsibility of the family fell on the elder sister. When her younger brother was admitted to university, to raise his tuition fees, the sister exchanged marriage for a 100,000 bride price. As time flew by, the younger brother, who had achieved success and fame abroad, learned of his sister's suffering and returned with three heavy gifts of gratitude. He severely punished those who had once bullied his sister, richly rewarded the benefactors of the past, and wrote a deeply affectionate repayment to his sister with love and gratitude, highlighting family loyalty and responsibility.
