I drew a lot. What does it mean to turn rusty iron into gold?

It means that with the help of noble people, gold will always shine.

Drawing lots is a folk custom in China, and it is also 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.
