[Shan Hai Si Zhi] Yin and Yang Volume

In the ancient "Zhao Dynasty", the world was divided into three parts: the northern Xinjiang grassland, the Central Plains farming, and the southern wilderness miasma. According to folklore, the "Shan Hai Division" was established by the ancient Emperor Yu, who was responsible for "controlling mountains, regulating water, and regulating yin and yang." In the past dynasties, the "Storm Book" and "Mountain and River Records" were used as the basis to deal with disputes between humans and monsters.
