Lin Wantang, a modern social animal, accidentally traveled through time and became Su Wantang, the most unpopular concubine in the magistrate's office of the Jin Dynasty. She was mistreated by her stepmother because of her reputation as a "mother-killer" and was forced to marry her sister to the Dingbei Prince's Palace for happiness. Faced with the dilemma of coarse cloth, rags, and leftovers from the cold stove, she used the tenacity she had learned in the modern workplace to deal with the house fight: she used the flower arranging skills she learned in her previous life to amaze the old lady, she used logical reasoning to solve the kitchen poisoning case, and she used "down-to-earth" limericks at the poetry meeting to expose her sister's fake talent. I thought that the happy marriage was a dead end, but I met Gu Zhao, the prince of Dingbei who was cynical on the surface but sincere in reality - he would secretly stuff candied fruits into her dressing box, and jumped to save her when she was pushed into the water by her eldest sister. After learning that she had been chronically poisoned by her stepmother, he searched through medical books all night to find the antidote. And her sister-in-law Liu Mingzhu, who had always regarded her as a thorn in her side, gradually turned dark because of her love for Gu Zhao. She went from throwing dirty water to paying for murders, and even colluding with the enemy's secret guards to set up a trap. However, Wan Tang used the wisdom of "repaying him with kindness" to resolve it. When the mystery of his life experience (he turned out to be the orphan of the late empress) and the undercurrent of the court surfaced, Wan Tang and Gu Zhao worked together to break the situation. While healing each other, they staged a two-way redemption of "Cinderella" and "Little Sun".
