Note: Calligraphy went in and out of Yin and Shang Dynasties for two weeks, Qin and Han Dynasties, and people with lofty ideals could be found.
Tang's "New Interpretation of Linchi" says: "Grass is the most expensive. If the pen is not empty, it is not round; If the pen is not true, it is not calm. Dedicated virtual pen, like near oil; Only with a real pen is it clumsy. Seeing the virtual and seeing the real means that the virtual and the real coexist. Calligrapher's Secret: Beauty is combined, while God is separated. Between clutch and clutch, it's wonderful. This is also true and false. "
Note: the reality of calligraphy is the key to writing, and the combination and separation are in the structure. Only when the two are well coordinated can we properly grasp the "degree" and write good works.
