A modern businessman traveled back to ancient times，he landed in the body of a man about to be married as a matrilocal husband into a family of cloth merchants. He then began incorporating modern methods and ideals to help his friends and battled corrupt local businesses. Faced with family affairs, national affairs, and world affairs, he went forward courageously. From a little son-in-law who didn't care about, he grew up to truly stand up for the world, set his life for the people and live up to the times, and also changed the times.
