Introduction to the account book: The account in Jiulian Mountain’s “account book” refers to cloth. There are generally two ways of writing accounts, one is a written account, and the other is a picture account. It is strictly forbidden for outsiders to watch when writing accounts. It is said that there is no drafting, just writing. What is even more strange is that the account writer himself does not understand the account written by him. Therefore, after the account is written, a ceremony must be held at a selected time to open the account in front of the believers and ask the "account opener" to "open the account". The "account opener" is the person who explains the account book, and understands the account book by singing sutras or dancing. After the "account maker" has finished opening the account, the account writer will burn the account book clean in front of the gods. This is "paying the account." At this point, the fate of an account book has been fully explained from beginning to end.
