The brushwork of seal script is thin and powerful, with many straight lines. There are Fang Bi, round pen and sharp pen at the beginning. The style of seal script is serious and the white cloth is rigorous. Learning seal script can avoid weakness, vulgarity, barrenness and inclination.
The extended data seal script is gradually evolved from the Qin characters in the Spring and Autumn Period and the Warring States Period. Because it is an official book, Xiao Zhuan is only suitable for major occasions, such as remembering merits and carving stones, measuring imperial edicts, playing tiger symbols and so on. The style of standard seal script is neat arrangement, round strokes, even and long lines, showing a solemn and beautiful style.
"Da Zhuan" is the writing of Zhou Dynasty. In a broad sense, Oracle Bone Inscriptions and Jinwen belong to Da Zhuan. In the Zhou Dynasty, after hundreds of years of chaos, different languages were developed in different countries, and we can regard them as all kinds of big seals.
After the unification of the six countries, Qin synthesized the seven languages and formulated a common language, namely Xiao Zhuan. Modern Chinese characters evolved from Xiao Zhuan. Although Xiao Zhuan has a history of nearly 2200 years, it still appears on many occasions today, especially in artistic design and calligraphy and painting works.
