"Thousand Years of Business" tells the story of Chen Yan, a modern financial analyst who accidentally traveled back in time to the Xining period of the Northern Song Dynasty and became the son of a declining businessman. With modern business knowledge and financial means, he started from a small grain shop and gradually established a business empire spanning Asia and Europe. In the process of growing up, he not only had to deal with disputes in court and secret wars in shopping malls, but also had to find a balance between old and new values. He also had complex emotional entanglements with three women with very different personalities. When modern thinking collides with ancient rules, and when personal ambition encounters the righteousness of the family and the country, how will Chen Yan rewrite his life and the business landscape of this era?
