Su Yan, the Investor of the Year, suddenly collapses at a prestigious awards ceremony attended by countless admirers. After being reborn, she finds herself in Republican-era Suzhou as Su Jinxiu, the destitute daughter of a textile mill owner whose family has been ruined and who was forced to jump into a river. Surrounded by a scheming scoundrel and ruthless businessmen determined to crush her, she faces seemingly impossible dead ends at every turn. Drawing on her advanced business knowledge, she introduces group-buying discounts and livestream shopping with immersive fashion shows to the Republican era, using an asset-light business model to break through the obstacles. As she navigates the treacherous business world, a mysterious figure repeatedly lends her a helping hand from the shadows. From fighting for survival in desperate circumstances in Suzhou to making her way through Shanghai, she rises to prominence in Shanghai's business community and builds a vast business empire, including the legendary Paramount Ballroom. The world comes to know her as 'Half of Shanghai,' Su Bancheng.
