The heroine is the planning director of an advertising company in modern times, but accidentally travels back to the Tang Dynasty and Wuzhou period. There is no system, no space, just marketing theory and worldly wisdom. She started as a bookstall hawker in the West City of Chang'an. With modern marketing methods such as "hype concept", "hungry marketing" and "brand premium", she set off a series of business storms in the hierarchical Tang Dynasty, and eventually established her own business empire, and changed the worldly vision of "scholars, farmers, industry and commerce".
