Seal script is a general term for big seal script and small seal script. The brushwork is thin and powerful, with many straight lines. There are Fang Bi, round pen and sharp pen at the beginning, and many "hanging needles" at the end of the pen. Big seal script refers to inscriptions on bronze inscriptions, bronzes and six-country scripts, which retain the obvious characteristics of ancient hieroglyphics. Xiao Zhuan, also known as "Qin Zhuan", is the common language of Qin State.
The simplified font of Dazhuan is characterized by uniform and neat shape, which is easier to write than Zhuan. Small seal script is slender, symmetrical, even in strokes, dignified and beautiful.
Extended data:
Since the Han Dynasty, it is generally believed that Da Zhuan was written by Zhou Xuanwang Taishi Zhuan (827 BC). Among the stone carvings handed down from ancient times, Shi Guwen is the most representative. This kind of stone tool is undoubtedly the oldest and most reliable stone cultural relic in China. It is now in the Palace Museum in Beijing.
Shi Guwen has an important position in the history of calligraphy. The oldest rubbings known in the world are Song rubbings collected by Fan Tianyi Pavilion in Ningbo, Zhejiang Province. The font is roughly between Zhou and Qin Xiao 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.
