Chronicles of the Shanhai Bureau: Yin and Yang

In the ancient Great Zhao dynasty, the realm was divided into three: the northern frontier grasslands, the agricultural heartlands of the Central Plains, and the miasma-ridden southern wilderness. Folk tradition held that the Shanhai Si had been established by the ancient Great Yu to “guard the mountains, regulate the waters, and balance yin and yang.” For generations, it had relied on the Register of Talismans and the Gazetteer of Mountains and Rivers to resolve conflicts between humans and demons.
