The male protagonist is the largest salt merchant in southern Zhili and owns half of the city's wealth at a young age. The marriage with the Su family is a win-win situation of "combination of government and business". He had known for a long time that the eldest lady of the Su family was not easy to deal with, but he did not expect that she would dare to escape and change someone on the wedding day. What's even more outrageous is that the third sister of the Su family actually got on the sedan chair - everyone hid it from him.
