"The Story of Promotion in the Queen's House" is set in the back house of an ancient official family and tells the story of the counterattack legend of Yun Shu, a maidservant who came from a humble background. In the back house, an arena where the jungle is the strongest, while others are busy vying for favor and gossiping, Yun Shu chooses to use the "juan" as a blade to quietly accumulate strength - copying medical books to develop her ability to recognize medicines, studying agricultural economics to master vegetable garden management, and figuring out unique accounting methods. She was once regarded as an outlier who was asking for trouble, a soft persimmon without any threat, but when her mistress was in emergency, she turned the tide with the "A Thousand Gold Wings" written by herself, and in the face of difficulties, she used clear accounts and clever strategies to save money. Yun Shu has proved with his actions that "juan" is never internal friction, but makes everything a springboard for promotion. Relying on her vision and structure, she counterattacked from the ninth-level maid all the way to the aunt in charge, walked out of the Tongtian Avenue in the back house, and became her own backer.
