Part 3 Xiaozhuan
When Chinese history came to Qin Dynasty, Qinshihuang made China a union. He launched the first reform of Chinese character. The character used by Qin kingdom was sorted out and simplified and used in the united country, and the other (six) kingdoms’ characters were banished. This reformed character was named xiaozhuan or Qinzhuan which was originated from the former characters, but its lines are the neatest and most well-balanced, and the shapes of it are even firmer. It is very important, for it is the end of the ancient Chinese characters (jiaguwen, jinwen, xiaozhuan) and the beginning of the modern Chinese characters (lishuu, caoshu, xingshu, kaish).
Part 4 Lishu
Lishu was developed from xiaozhuan in Qin Dynasty, and mainly used in Han Dynasty and Wei Dynasty. Compared with xiaozhuan, the strokes of lishu are straighter and squarer, and it removes the feature of picture of Chinese character. Since then, the shades of Chinese characters have almost been stabilized. Of course, there are some differences in different scripts.
Part 5 Caoshu, Xingshu and Kaishu
Caoshu is from lishu in Han Dynasty, and grown up in Jin Dynasty. It is the fast writing form of lishu, called zhangcao first. Its developed type is called jincao (modern caoshu).
Xngshu and kaishu are also developed from lishu in Han Dynasty and are popular in Wei Dynasty, Jin Dynasty and South-north Dynasty. They are very practical, and used widely till today.
