The Chinese writing system, also known as Hanzi, is one of the oldest continuously used writing systems in the world. It is estimated to have been developed over 3,000 years ago and has undergone significant evolution over time. The earliest forms of Chinese characters were found on oracle bones and tortoise shells, known as Jiaguwen, dating back to the Shang Dynasty (c. 1600–1046 BC). These characters were primarily pictograms, representing objects or ideas through simple drawings. As the Chinese civilization advanced, the writing system evolved into a more sophisticated form known as Zhuan Shu (seal script) during the Qin Dynasty (221–206 BC). This script featured more abstract and stylized characters that were widely used for official purposes. During the Han Dynasty (206 BC–220 AD), a more streamlined and standardized script known as Kai Shu (regular script) emerged as the predominant form of writing. This script laid the foundation for the modern Hanzi characters used today. In the centuries that followed, various script styles, such as Xing Shu (running script) and Cao Shu (cursive script), were developed to meet different practical and artistic needs. These styles added fluidity and expressiveness to the Chinese writing system. Today, the Chinese writing system continues to be an integral part of Chinese culture and identity. Its rich history and evolution reflect the enduring legacy of the Chinese civilization.
