These include China, Japan, Korea, and to a lesser extent, Vietnam. In addition to being an art form in its own right, calligraphy has also influenced ink and wash painting, which is accomplished using similar tools and techniques. The East Asian tradition of calligraphy originated and developed from China, specifically the ink and brush writing of Chinese characters. There is a general standardization of the various styles of calligraphy in the East Asian tradition. Calligraphy has also led to the development of many other forms of art in East Asia, including seal carving, ornate paperweights, and inkstones."
