Signature: Generally, it comes from stories, allusions, the Book of Songs, the Book of Changes and Buddhist scriptures, representing a signature theme.
Signing: Four fables written according to their signatures generally come from poems and folk customs, and are mostly compiled by low-ranking people such as temples and guests in Antang. In the past, temples were responsible for receiving donors, begging for alms, drawing lots and collecting incense money. In short, they eat and dress in temples and earn some extra money. Therefore, many autographs and "poems" have no cultural level, and most of them are to persuade people to donate more incense to goodness in order to bless the gods.
Postscript: Most of them are from five lines of gossip and Yijing. They are divinatory symbols taken by some quack doctors according to the number of signs, which are used to answer various questions of candidates and are an extension of the interpretation of signs.
Juxtaposition: With the forehand divination or signature, make a concrete explanation of fame, fortune, marriage, looking for a job, etc. in one sentence, mainly used to ask questions to candidates. So what you originally wanted was "fame", but your painting "personals" can also give you the answer.
