China's Chinese characters have undergone several changes. Thank you.

1 Oracle bone inscriptions on Oracle bones mainly refer to Oracle bone inscriptions in Yin Ruins, which were carved (or written) on tortoise shells and animal bones by the royal family in the late Shang Dynasty (14 ~1century). It is the earliest and most complete ancient Chinese character discovered by China. Bronze inscriptions refer to the words carved on bronzes in the Yin and Zhou Dynasties, also known as Zhong Dingwen. Shang and Zhou Dynasties were the bronze age, with the tripod as the representative ritual vessel and the bell as the representative musical instrument. "Zhong Ding" was synonymous with bronze ware. Therefore, Zhong Dingwen or inscriptions on bronze refers to inscriptions cast or carved on bronzes. Shi Guwen, the representative figure of Da Zhuan, was named after Zhou Xuanwang's biography of Taishi. On the basis of the original text, he transformed it and got his name because it was engraved on the stone drum. It is the earliest stone carving text that has been circulated so far, and it is the ancestor of stone carving. It began in the late Western Zhou Dynasty and traveled in Qin during the Spring and Autumn Period and the Warring States Period. The fonts are similar to those of Qin Zhuan, but the configurations of glyphs overlap. 4 Xiao Zhuan Xiao Zhuan is also called "Qin Zhuan". During the Qin Dynasty, Li Si was ordered to unify the characters, which was called Xiao Zhuan. It was popular in the Qin Dynasty. The shape is long, even and neat, and it evolved from Da Zhuan. In the Eastern Han Dynasty, Xu Shen said, "Qin Shihuang is the first emperor in the world, ... but he is not in harmony with Qin Wen." Li Si wrote Cang Xie, CZ ordered Zhao Gao to write, loved the calendar, and Grandmaster Hu Wujing wrote erudition: "They all took the stone script seal script, or saved a lot of changes, so-called small seal script." Today's remains (Langyatai Stone Carving) and "Taishan Stone Carving" are masterpieces of Xiao Zhuan. 5 Lishu Lishu basically evolved from seal script, mainly changing the round strokes of seal script into square folds, which makes writing faster, and it is difficult to draw round strokes when writing with pigments on wooden slips. Official script is also called "official character" and "ancient book". It is a font produced on the basis of seal script to meet the needs of convenient writing. The seal script is simplified, and the uniform circle lines of the seal script are changed into straight strokes, which is convenient for writing. Official script can be divided into "Qin Li" (also called "Guli") and "Han Li" (also called "Golden Calendar"). The appearance of official script is a great change in ancient writing and calligraphy. Official script is a common solemn font in Chinese characters, with a slightly flat writing effect, long horizontal drawing and short straight drawing, and pays attention to "swallow tail of silkworm head" and "twists and turns". It originated in the Qin Dynasty and reached its peak in the Eastern Han Dynasty. Calligraphy is known as "Han Li Tang Kai". It is also said that official script originated in the Warring States period. Official script is relative to seal script, and its name originated from the Eastern Han Dynasty. The appearance of official script is another great change of China characters, which brings China's calligraphy art into a new realm, is a turning point in the development history of Chinese characters, and lays the foundation for regular script. Official script is flat, neat and exquisite. In the Eastern Han Dynasty, stippling such as skimming was beautified as upward provocation, with different degrees of severity and artistic beauty of calligraphy. Styles also tend to be diversified, which is of great artistic appreciation value. 6 Regular script Regular script is also called official script, or real script. Its characteristics are: square shape, straight strokes, can be used as a model, hence the name. Began in the Eastern Han Dynasty. There are many famous regular script writers, such as Ou Ti (Ou Yangxun), Yu Ti (Yu Shinan), Yan Ti (Yan Zhenqing), Liu Ti (Liu Gongquan) and Zhao Ti (attached). A font between regular script and cursive script can be said to be cursive script or cursive script. It is to make up for the shortcomings of slow writing in regular script and illegible cursive script. The brushwork is not as sloppy as cursive script, and it is not required to be as correct as regular script. There are more methods of mold opening than cursive writing, which is called "mold opening". Cursive calligraphy is more than modular method, which is called "cursive calligraphy". Running script was produced in the late Eastern Han Dynasty. 8 cursive script: a style of Chinese characters. Formed in the Han Dynasty, it evolved on the basis of official script for the convenience of writing. There are Cao Zhang, Cao Jin and Crazy Grass. There are rules to follow in the changes of strokes, such as the urgent chapter of the Three Kingdoms Wu in Songjiang Edition. Today's grass is eclectic and fluent, and its representative works include "Early of the Month" and "Timing" by Wang Xizhi in the Jin Dynasty. Mad grass appeared in the Tang Dynasty, represented by Zhang Xu and Huai Su, and its brushwork was wild and uninhibited, which became an artistic creation completely divorced from practicality. From then on, cursive script was only the works of calligraphers imitating Cao Zhang, Cao Jin and Kuangcao. Masterpieces such as Zhang Xu's Abdominal Pain Post and Huai Su's Autobiography Post. Cursive script is a font produced for the convenience of writing. It began in the early Han Dynasty. At that time, it was "Cao Li", that is, scribbled official script, which gradually developed into a kind of "Cao Zhang" with artistic value. At the end of the Han Dynasty, Zhang Zhi changed "Cao Zhang" to "modern grass", and the character style was formed in one fell swoop. In the Tang Dynasty, Zhang Xu and Huai Su developed into "weeds", with continuous strokes and changeable glyphs.
