The word calligraphy is imported. As we all know, the cultural exchange between China and Japan began as early as the Tang Dynasty. After the art of calligraphy spread to Japan, it undoubtedly merged and evolved with Japanese local culture and became a way of practice. The introduction of grades makes the quality of calligraphy a kind of hard-to-measure standardized art. Although this quantitative standard is impartial, it undoubtedly lowers the threshold of traditional calligraphy education from an intentional but wordy state, and makes calligraphy, a seemingly unfathomable skill, a cultural phenomenon that the people can accept and love. It is a way worth learning.
