Overview of the meaning of Jiugongge
A boundary paper used for temporary writing of inscriptions. Draw a "well" in the square and divide it into nine equally divided squares. Because the shapes and positions of the nine squares are similar to those of the Nine Palaces in ancient Tang Ming, they are named. According to legend, this method originated from Ou Yangxun, a famous calligrapher in Tang Dynasty. Refers to the beat of a poem clock. The poems of the upper and lower sentences are not the same, but the literal words are closely matched, and the content and form blend and interact with each other, just like the Nine Palaces in ancient Tang Ming, hence the name.
On the right are eight squares filled with numbers, and on the left is a table named "Your Numbers" with a coating on the surface.
