Yang Gong refers to Yang Junsong, a famous master of geomancy in Tang Dynasty. Because he worked for the people all his life and won their love, people called him Yang Gong. Yang Junsong was too honest and kind, persecuted by some vicious people, and regarded Yang Junsong as a thorn in his side and a thorn in his flesh. Yang Gong was killed thirteen times in his life, but Yang Junsong's integrity and actions were sheltered by the gods, so he was able to save the day every time.

Later, according to the time nodes of these thirteen murders, Yang Junsong called these thirteen times "thirteen taboos", which became what people called "Yang Gong taboos".
