Swapping marriage refers to the mutual exchange of daughters from two families as daughters-in-law.
This practice is common among families so poor that they can't afford to eat or marry off their sons; it's also known as "sister exchange".
However, Wen Wan, having grown up, had never seen anyone practice marriage swapping.
It had been nearly ten years since Dalang's wife died, and only then did someone from the Wang family propose the swap, which seemed so suspicious no matter how you thought about it.
Wen Wan still remembered Song Wei telling her that after the eldest sister-in-law passed away, the Song family compensated the Wang family quite a lot, with just silver coins amounting to dozens of taels.
Several dozen taels ten years ago would be equivalent to several hundred taels today.
At that time, the Song family had no financial foundation; all that money was pieced together by Old Song and Granny Song, who even ended up with a considerable amount of debt because of it.
