Basically there are very few, almost none
Seal script is the oldest calligraphy style in calligraphy. It can be roughly divided into large seal script and small seal script. We often refer to the seal script before the Qin Dynasty unified China. Seal scripts are collectively referred to as large seal scripts, such as oracle bone inscriptions, bronze inscriptions, stone drum inscriptions, etc. In 221 BC, Qin Shihuang unified China and adopted the "carriage on the same track, calligraphy on the same text", and was unified into small seal script by Prime Minister Li Si and others. Later, due to the change of dynasties and the changes of the times, the calligraphy styles of Chinese calligraphy also rose and fell, and major calligraphy styles such as seal script, official script, regular script, running script and cursive script appeared successively, promoting the continuous development of calligraphy art. The following will give you a brief introduction to the development history of seal script.
Ancient times (pictographic symbols)
The emergence of Chinese characters can be traced back to the Neolithic Age, and characters similar to symbols appeared in the ancient times thousands of years ago.
"Book of Changes. Xi Ci Xia": "In ancient times, people were governed by knotting ropes, and later generations of saints changed it with written deeds." The book is the written text, and the deed is the engraved mark. "Shiben. Zuopian" of the Warring States Period: "Cangjie wrote the book." Cangjie (jié) was the historian of the Yellow Emperor, which facilitated the distribution and exchange of government orders. Xu Shen's "Shuowen Jiezi": "Cangjie, the historian of the Yellow Emperor, saw the traces of the hooves of birds and beasts, and knew that the principles could be distinguished from each other, so he first made a written contract."
Shaanxi, Shandong, etc. Pottery from the Neolithic period (5,000 to 6,000 years ago, earlier than the Yellow Emperor's time) was unearthed in the ground, with symbols engraved on them, similar to hieroglyphics. For example, Xi'an Banpo pottery, Erlitou pottery, Dawenkou pottery, or Gansu Majiayao pottery have signs of characters similar to seal scripts, although overall they are still patterned characters or pictographic characters. They are mainly pictographic symbols with the characteristics of words.
