The protagonist of the 50-episode South Korean TV series "Businessman" Lin Sangwo, since he was young, studied Chinese under his father's strict guidance. He wanted to fulfill his father's wish and become the "First Translator" of Korea... As Sangwo grew up, his father began to realize that in the then corrupt examination system, the dream of becoming a translator might never be achieved. So, he put down the proud self-respect of a man of letters and borrowed money from Hong Dezhu, who had already become the richest person in Yizhou, and set sail with Sangwo... However, when they were full of hope and planning for the future, a disaster fell upon them. In order to save himself, Park Choum of the Songchang House sent Sangwo's father to the guillotine, making him a wronged soul. Sangwo was demoted to an official slave with a heart full of revenge, living a life worse than pigs and dogs. He escaped time and again, only to be caught back each time.
