Or calligraphy: China calligraphy is an ancient art form of writing Chinese characters. From the characters on Oracle Bone Inscriptions's shoulder blades and tortoise shells, to the cursive inscriptions (bronze characters), and later the big seal script, small seal script and official script, and then to the more standardized cursive script, regular script and running script in the Eastern Han Dynasty and Wei and Jin Dynasties, China's calligraphy still maintains its charm as an art form. Chinese characters are not only one of the oldest characters in the world, but also correspond to three different sounds. In addition, many Chinese characters are hieroglyphics, that is, phonography, which means that many Chinese characters look or sound the same. No wonder Chinese characters are so difficult! Based on the rich characteristics of Chinese characters, calligraphy, as an art form, is handed down by ancient intellectuals and cannot be expressed in words. An ink pen, sipping a drop of ink, swishes, rotates, accelerates, and then suddenly presses it to end. The birth of Wang Xizhi's Preface to Lanting, the birth of Four Treasures of the Study and the birth of dynamic seal cutting added luster to China's calligraphy.
