The evolution of Chinese characters is a process of gradually standardizing and stabilizing Chinese fonts. Small seal script makes the number of strokes of each word fixed; Lishu has formed a new pen system, and the font has gradually become flat and square.
After the birth of regular script, the font of Chinese characters tends to be stable, and the basic strokes of "horizontal, vertical, left, point, pick and fold" are determined, which further standardizes the stroke shape and fixes the number and order of strokes of each character.
Extended data:
At present, archaeologists have unearthed more than 1.6 million pieces of Oracle bones. Some are complete, and some are just fragments without written records. According to statistics, there are more than 4,000 words on all these Oracle bones, of which about 3,000 words have been verified by scholars, and among these 3,000 words, scholars have interpreted more than 1000 words.
Oracle Bone Inscriptions is a mature and systematic writing, which laid the foundation for the development of Chinese characters in later generations. Since then, Chinese characters have gone through various forms, such as inscriptions on bronze, seal script, official script and regular script, and have been in use ever since. The characters of Japan, Vietnam, South Korea and other countries are all created on the basis of Chinese characters.
