The changes of Chinese characters in different periods mainly include the following aspects: 1. Form evolution: The form of Chinese characters has undergone great changes in the evolution. From Oracle Bone Inscriptions, inscriptions on bronze, seal script, official script to regular script, the fonts in each period have their own unique characteristics. 2. Writing style: With the development of culture, people's writing styles are constantly evolving, from carving Oracle Bone Inscriptions with a carving knife to writing official script and regular script with a brush, each writing style will affect the form of Chinese characters. 3. Phonetic change: With the evolution of Chinese characters, the pronunciation of Chinese characters is constantly changing. For example, in ancient times, the word "book" was pronounced as "sh", but in modern times, it is pronounced as "sh" or "sh ǔ". 4. Abandon words: Chinese characters may be abandoned in different periods, that is, some Chinese characters are abandoned because of low frequency or redundancy.
