Drawing lots is a folk custom in China and one of the forms of divination. At present, Taoist temples, temples and folk temples have mostly placed sign boxes for people to draw and ask for directions. Like gossip, drawing lots is a popular forecasting method for ancient people in China to judge good fortune and bad fortune. The basis for judging good or ill luck is the number of poems signed and the allusions of poems signed.

Of course, the lottery has a strong mystery, which includes the subjective speculation of the lottery players. It is an idealistic thing, and we don't need to talk about it here. But every sign must be signed, and the signed poem is an allusion, and these poems and allusions are created by ancient literati. The content is rich and colorful, including many truths of theology, literature, history, religion and philosophy, which we have to explore and study.
