Red cloth: mainly used at the entrance of Xianjiatang below. For example, the cloth used to write the hall card (immortal list) at the entrance of a hall may be red, especially the hall card that records the information of immortals in the lower bound, such as Chang Python. It is usually written in red cloth.
Yellow cloth: mostly used for immortals or special occasions. For example, in some local customs, the whole hall above, that is, the list of halls where immortals such as the Jade Emperor and the Queen Mother are recorded, will be written in yellow cloth. In addition, in some cases, yellow cloth will be used to show respect for the gods who were given the title of emperor.
