Lin Zhiyun was a notoriously lazy and foolish girl in the surrounding villages, yet she had a perfect marriage arranged from childhood with Xu Xiucai, who was now her husband. Her older cousin, Lin Xiuyue, on the other hand, was a famously clever and skillful girl, yet she had a terrible marriage arranged from childhood with Shen Junchuan, a lame scoundrel. People in the village often said that it would be better if the sisters' marriages could be switched. So, on the day of the sisters' weddings, the elders of the Lin family secretly switched the brides.

Not long after, everyone discovered that Lin Xiuyue, the good girl who married into the Xu family, was good at nothing, while Lin Zhiyun, the lazy girl who married into the Shen family, was proficient in spinning, weaving and embroidery. Together with the prodigal son Shen Junchuan, they lived a good life.
