1. Oracle Bone Inscriptions is the earliest China script we have found so far, which was carved on tortoise shells or animal bones in Shang Dynasty. These words are mainly used to predict good luck or bad luck. In the process of divination, tortoise shells were first burned with fire, and cracks appeared on them. According to this kind of crack, people in Shang Dynasty predicted good or ill luck, and recorded divination events and results on tortoise shells. These words engraved on tortoise shells or animal bones are called ".

2. Jinwen

The custom of casting inscriptions on bronzes became popular in the late Shang Dynasty and reached its peak in the Zhou Dynasty. The pre-Qin dynasty called copper gold, so later generations called the words on ancient bronzes bronze inscriptions. Because Zhong and Ding played an important role in various bronze inscriptions in the Zhou Dynasty, they were also called "Zhong Dingwen". The application of bronze inscriptions lasted for more than 1200 years from the early Shang Dynasty to the Qin Dynasty's destruction of the Six Kingdoms. Like modern cast iron products, bronzes are usually cast in clay models, which are called "Fan Tao". Bronze inscriptions are pre-carved and then cast on the Fan Tao, and a few are directly carved after bronze casting. Because Fan Tao is soft, it is easier to carve than tortoise shells and animal bones, and the early bronze inscriptions are stronger than Oracle Bone Inscriptions's pictures, which are closer to the original characters.

3. Xiao zhuan

"Turn" is originally a combination of small turn and big turn. Because it is customary to call Wen Zhuan Da Zhuan, later generations often call him "Wen Zhuan". Xiao Zhuan, also known as Qin Zhuan, is a font that was omitted from Da Zhuan. It originated in the Qin State at the end of the Warring States Period and prevailed in the Qin Dynasty and the early Western Han Dynasty. During the Warring States period, countries were separated, and their characters were not uniform and their fonts were quite complicated. So Qin Shihuang unified the world characters with Qin characters, abolished various forms different from Qin characters in six countries, omitted and deleted the original characters of Qin, and absorbed some simplified and popular fonts from folk characters and standardized them, forming a new font-Xiao Zhuan.

China characters developed to the stage of Xiao Zhuan, and gradually began to finalize the outline, strokes and structure. The pictographic meaning is weakened, which makes the characters more symbolic and reduces the confusion and difficulty of writing and human reading. This is also the product of the first large-scale use of administrative means to standardize writing in the history of China. The Qin Dynasty unified the national characters with the sorted seal script, which not only basically eliminated the phenomenon of different lines of characters in different places, but also greatly changed the situation of different fonts in ancient Chinese, and played an important role in the development history of China characters. In addition to Xiao Zhuan, it also includes Oracle Bone Inscriptions and Jinwen, collectively referred to as Chinese characters; The development of ancient philology had a great influence on the study of ancient history, philosophy, economy, law, culture, science and technology in China.

4. Although Xiao Zhuan is a relatively neat rectangle and its structure is composed of even and round lines, it is quite inconvenient to write and the font is more complicated. Due to various shortcomings, a new font appeared rapidly among the people. Xiao Zhuan's dignified and neat, rounded and curved lines were written in square folds. It is said that this font was very popular among junior officials, craftsmen and slaves at that time, so it was called "official script". In the Han Dynasty, official script replaced Xiao Zhuan as the main font, and the development history of China characters broke away from the ancient writing stage and entered the official script stage. After the Han Dynasty, Xiao Zhuan became an ancient font mainly used for carving seals and bronze inscriptions. The formation of official script changed the characters following the shape of objects into simplified Chinese characters composed of straight strokes, which greatly improved the writing speed. China script changed from seal script to official script, which is called "official script change". The official script reform is an important turning point in the development of China characters, ending the stage of ancient Chinese characters and making China characters enter a more stereotyped stage. After the official script was changed to official script, the characters are close to the existing characters and easier to identify than the ancient characters.

5. The regular script created by Zhong You in the Eastern Jin Dynasty experienced many changes in Wei, Jin, Southern and Northern Dynasties, and was basically finalized after Sui and Tang Dynasties. After the finalization, the regular script is exquisite and rigorous in strokes and structure, such as the works of Ou Yangxun, a famous calligrapher in the Tang Dynasty.
