The Sousho style 草書 or “grass writing” refers to the cursive style. A style that prioritizes the fluidity and continuity of the writing when one stroke seeks another and the maximum contact on the paper during its execution. For this reason, the letter is synthesized in rhythmic movements, thus showing a richness in the strokes with changes worked in a very subtle way. The beauty of the stroke is more important than the legibility of the character itself. The pioneer of cursive writing was Zhang Zhi 張芝 or Tsao Sheng 草聖, during the Han dynasty. He was a person with very few resources, so he could not afford to buy paper. He studied on whatever cloth he had available. After each practice, he washed his brushes, his ink stone and the cloths in the pond near his house. Legend has it that, finally, the water in the pond turned completely black. Even today in China, the phrase "in front of a pond," Lin Chi 臨池, means studying calligraphy.
