The Chen and Su families were family friends. At that time, the Su family was just a small salt merchant with two salt wells, and the Chen family's grandfather only held a casual position in the government. By chance, the two families got acquainted, and they supported each other in the turbulent times. Fang became the general merchant of the Lianghuai salt merchants, and the Su family became the governor. The Chen family and the Su family, who had gone through many hardships, had made a marriage arrangement since their ancestors, intending to form a good marriage and marry each other, not wanting both families to be prosperous. It was not until the fourth generation that the birth of Su Manli finally made the agreement between the two surnames come true.
