When Tong Yue'e returned to the eve of her wedding, the first thing she did was to tear up the marriage that was trapping her. The Song family wanted to use her to pay off their debts, and her parents' family wanted to use her to exchange money, but she no longer accepted her fate. Starting from a betrothal gift account and an IOU, she recovered the money, established rules, protected her reputation, set up stalls, shops, and factories, and took back everything that was taken away step by step. Others rely on words to argue, but she relies on accounts, goods, and evidence to stand up, and makes all those who have plotted against her bow their heads one by one.
