Why do you draw symbols with brush strokes?

In fact, there is no difference between Taoist symbols of different colors. The real difference is the raw materials and personal ability used in drawing symbols. All Taoist symbols have no specific requirements, including ordinary white paper and yellow paper, which are generally based on local materials. Taoist painting symbols are matched with cinnabar and writing brush, and with the blessing of various spells, writing brush can show the characteristics of different colors and symbols more delicately, so it is best to use writing brush.
