Evolution of Chinese characters:

Chinese characters are one of the characters with the longest use time, the widest use space and the largest number of users in the world. The creation and application of Chinese characters not only promoted the development of China culture, but also had a far-reaching impact on the development of world culture. About 6000 years ago, in Banpo ruins and other places, more than 50 kinds of carving symbols have appeared.

Basic introduction:

It is neat and standardized and has the characteristics of simplified Chinese characters. Scholars believe that this may be the bud of Chinese characters. The Chinese character formation system is the Shang dynasty in BC 16. Archaeology confirmed that in the early Shang Dynasty, Chinese civilization had developed to a fairly high level, and one of its main features was the appearance of Oracle Bone Inscriptions. Oracle Bone Inscriptions is an ancient writing carved on tortoise shells and animal bones.

In Shang Dynasty, the king had to do divination before doing anything, and Oracle Bone Inscriptions was the tool of divination. Oracle Bone Inscriptions should be treated before use. Remove the flesh and blood from the Oracle bones first, and then cut and smooth them. Then, use a knife to drill a notch on the inside of the nail or the back of the animal bone. The arrangement of these gaps is orderly.

A fortune teller or wizard engraves his name, the date of divination and the questions to be asked on the Oracle Bone Inscriptions, and then burns the hole in the Oracle Bone Inscriptions with a torch. The cracks that appear when these depressions are heated are called "signs". The wizard analyzes the trend of these cracks, obtains the result of divination, and engraves the divination on the Oracle bone. After the divination came true, these Oracle bones engraved with Oracle Bone Inscriptions became official files and were preserved.

Classification:

Oracle Bone Inscriptions: In the late Shang Dynasty, most of the characters left on tortoise shells and animal bones by writing or carving were "Oracle Bone Inscriptions" and a few were notes. Most of Oracle Bone Inscriptions's characters conform to the principles of pictographic characters and knowing characters, with pictophonetic characters accounting for only 20%. Its characters are carved with a knife, some filled with cinnabar, and some written directly in ink.

Because Oracle Bone Inscriptions evolved from pictures and characters, it has strong pictograph, many characters and uncertain strokes. This shows that China's writing was not unified in the Yin and Shang Dynasties. Image Inscription in the Yin Dynasty: In the pre-Qin period, copper was called gold, so the words cast on bronze ware were called inscriptions, also known as Zhong Dingwen and Qi Yi. Compared with Oracle Bone Inscriptions, bronze inscriptions are more pictographic, showing ancient characters. The bronze inscription has a solid brushwork and vivid and natural image.

In the history of China, Xia, Shang and Zhou Dynasties made the most important contribution to philology. Shicheng is a historian in Zhou Xuanwang, and should not innovate for simplicity. Biography is also called Wen Shu, Biography of Shu, Shushu and History Book. Because it is written by history, it is called the Wen Shu of the world. Dazhuan can be found in Shuowen Jiezi and various Zhong Ding Yi wares collected by later generations. Among them, Shi Guwen in Zhou Xuanwang is the most famous.
