Chinese calligraphy is a form of calligraphy widely practiced in China and revered in the Chinese cultural sphere, which often includes Japan, Korea and Vietnam. The calligraphic tradition of East Asia originated and developed from China. There is a general standardization of the various styles of calligraphy in this tradition. Chinese calligraphy and ink and wash painting are closely related, since they are accomplished using similar tools and techniques. Chinese painting and calligraphy distinguish themselves from other cultural arts because they emphasize motion and are charged with dynamic life. According to Stanley-Baker, "Calligraphy is sheer life experienced through energy in motion that is registered as traces on silk or paper, with time and rhythm in shifting space its main ingredients." Calligraphy has also led to the development of many forms of art in China, including seal carving, ornate paperweights, and inkstones.
