Well-round lattice is designed according to the popular aesthetic standard of golden section and the inherent structural characteristics of Chinese characters in China. Because its shape is round with a pound sign, it is named well round grid.

Traditional practice grids include Tian Zige, Mi Zige and Jiugongge. These grids (including later grids) all use mathematical methods to locate strokes of Chinese characters. Practitioners practice repeatedly to achieve the training goal of practice makes perfect. Compared with these traditional practice grids, the rounded grids are more in line with the visual aesthetics and the inherent characteristics of Chinese characters: the lines are not equally divided, but combined according to the visual golden section ratio; The composition of the outer circle and the inner side also coincides with the lifestyle and life style of China people. The special structural features of Chinese characters in China are fully reflected by the left-closing and right-opening, the upper part is tight and the lower part is wide, and the middle part is tight. Therefore, tic-tac-toe is not only an exercise of mathematical positioning, but also an exercise of returning to calligraphy itself. In the well circle, you can scientifically train the most important structure and strokes of calligraphy practice. The 24-character formula of well circle grid: horizontal and vertical, head high and feet long, middle palace tightened, left closed and right placed, upper strict and lower wide, symmetrical left and right.

The rounded grid helps users to quickly master the structure of Chinese characters, thus greatly reducing the difficulty of calligraphy practice (self-study) and increasing the interest and confidence of calligraphy practice.
