Chinese characters are one of the oldest characters in the world, with a history of over 6000 years. The earliest Chinese characters were Oracle Bone Inscriptions in Shang Dynasty about 1300 BC and later inscriptions on bronze, which evolved into seal script of Western Zhou Dynasty, followed by seal script and official script of Qin Dynasty, and official script prevailed in Han and Wei Dynasties. At the end of the Han Dynasty, official script was changed to block letters. Regular script prevailed in Wei, Jin, Southern and Northern Dynasties, and passed 1. The development of Chinese characters has experienced the evolution from ideographic, ideographic to pictographic, from pictographic to symbolic, from complex to simple. Except for a few Chinese characters, they are all one Chinese character and one syllable 1. Modern Chinese characters have developed from Oracle Bone Inscriptions, bronze inscriptions, seal script and seal script to official script, cursive script, regular script and running script. Chinese characters are a symbol of China's cultural heritage, and also an indispensable link to maintain Chinese dialects.
