To this day, the folk belief of "asking for a visa" still circulates in Eastern society, and people believe in the gods of heaven and obtain spiritual guidance through the ritual of burning incense and throwing a raft when suffering comes. The signed poems adopt the modern poetic style, and the difficult words implied in the verses have invisibly become an obstacle between the gods and the faithful. Therefore, it is hoped that by constructing the pictorial form of the signed poem text, it will be easier for the signatory to obtain enlightenment in the process of exploration. This research uses the method of literature analysis to illustrate the connotation conveyed by each signed poem with the help of a large number of historical texts. Then, using the fieldwork method, we will explore the modern situation of the City God Temple in Taiwan Province and the poetry signing culture of the temple, and use "illustration" as an expression method to visualize the results of the disapproval of the 60 Koshiko signed poems, so that the ancient signed poetry culture has a new era value transmission mode and open up a new trend of contemporary style.
