The Cheng Huangs look after definite jurisdictions and mirror the local officials of the human world by administering the underworld. After death, people are first examined by the Cheng Huang, then submit his conclusion to the senior minister, Yen Wang.
城隍保護固定轄區，對照人間地方官（陽官）統治陰間社會，人在死後要先經城隍審問終結，才轉呈閻王。
