"Great Feng Shui" takes Feng Shui and Lee Sung-gye, the first founder of the Joseon Dynasty, as its themes. It tells the story behind the founding of the Joseon Dynasty during the transition of dynasties in the early Joseon Dynasty. This drama does not focus on the plot. It is not about fighting for power, but recreating the scenes at that time through the lives of civilians, officials and businessmen. Ji Sang (played by Ji Sung) plays the role of a Feng Shui master who can see people's past and future and have innate talents. He uses Feng Shui to help Lee Sung Gyu (played by Ji Jin Hee) finally establish North Korea. Li Tinggen (played by Song Changyi) is Chi Shang's biggest competitor, and he is also a strange fortune teller.
