Grass script
Also known as Cursive Calligraphy. The Chinese character "Grass" (草) also refers to loose and sketchy styles. It's faster to write compare to other Chinese Calligraphy styles, but also hard to read. It is an abstract form of calligraphy styles, which means you can take on any other Chinese Calligraphy styles (such as Block script 楷書, Seal script 篆書) and apply this form to it, which would be turned into Cursive Block Script (草楷), Cursive Seal Script (草篆), etc.
