The main forms of the script are the seal form, official form, regular form, cursive form and running form that have 
been used by calligraphists, ancient or contemporary. These forms are closely interrelated , but each form has its own shapes and features , so , different methods are employed for writing them .
The Seal form includes tortoise script , bronze script , Warring States seal script and small seal script . The tortoise shell script already took care of coordination and aesthetics, with proportionate strokes, lively structures and even strokes. The arrangement of the lines was also aesthetic . The coordination and aesthetic arrangement was done carefully by the writer and carver . The bronze script was the inscriptions on bronze objects , originated from the tortoise shell script , began in the Shang Dynasty and flourished in the Zhou Dynasty . They were more standardized and more square and regular in forms . The distribution of the strokes was more proportionate and symmetrical . The writing technique was more varied .
The Warring States seal script in the Warring States period was also known as the Six Kingdoms script, represented chiefly by the “inscriptions on drum stones”. This script was more proportionate in form and was poised and elegant, vigorous and lively. The small seal script was developed on the basis of the Warring States seal script and was simpler in form . After the first Emperor of Qin unified China , the different forms of the seal script were standardized into the small seal . Its structures are long and round , with proportionate thick and thin strokes . The strokes were smooth and not sharp at the two ends . They were very aesthetic . The representative small seal calligraphy was the “stone carving of Mount Tai” written by Li Si in the Qin Dynasty . Other renowned small seal calligraphists in the later dynasties were : Li Yangbing , Yuan Zi and Song Xuxun in the Tang Dynasty , Li Dongyang in the Ming Dynasty , Wang Shu , Deng Shiru , Sun Xingyan , Gui Fu , Zhao Zhiqian , Yang Yisun and Wu Changshuo in the Qing Dynasty .
