The likenesses of the netherworld's twelve "ox demons and snake spirits" are affixed to the various shui zang, which are arranged in groups representing three different levels of the cosmos: the water, the netherworld, and heaven. In the water are the spirits of those who have died untimely deaths, as well as the righteous Water King and the evil Filth God.
水的上下還分別貼著十二尊牛鬼蛇神，按水中、陰間、天堂三種不同的宇宙空間排列，在水中的有冤魂、正義的水王和代表惡者的污穢神。
