During the Ming dynasty, Chinese Islamic traditions of writing began to develop, including the practice of writing Chinese using the Arabic script (xiaojing) and distinctly Chinese forms of decorative calligraphy.[5] The script is used extensively in mosques in eastern China, and to a lesser extent in Gansu, Ningxia, and Shaanxi. A famous Sini calligrapher is Hajji Noor Deen Mi Guangjiang.
