Chinese characters have gone through more than 6000 years of changes. The evolution process is: oracle bone script, golden script, big seal script, small seal script, official script, cursive script, regular script, running script.

The evolutionary dynasties are: (Yin and Shang) (Zhou) (Qin) (Han) (Wei and Jin)

The evolutionary process of Chinese characters can be briefly summarized into five stages: sound, shape, image, number and reason.

The Chinese characters have undergone many changes since the oracle bone inscriptions. According to historical facts, these changes can be roughly categorized into two main groups: reform and natural flux. Reform of Chinese characters refers to the process of people's conscious and active governance of Chinese characters, while natural flux of Chinese characters refers to the natural process of change of Chinese characters. Reform of Chinese characters is generally non-continuous, drastic, and accomplished in a short period of time; while the natural flux of Chinese characters is continuous, slow, and long-term.

Extended information:

The natural flux of Chinese characters has both temporal and geographic factors, which diversify their glyphs, sounds, and meanings, resulting in more and more variant characters, different readings of their sounds, and changes in their meanings, which lead to inconsistencies and irregularities in Chinese characters.

Therefore, after a period of natural evolution, people must reform the Chinese characters to make them standardized and unified. In addition, it is impossible for Chinese characters to be perfect and meet the needs of the development of productive forces in all periods of time as soon as they are created, so as time progresses, people also take the initiative to reform the Chinese characters to make them meet the needs of the continued development of productive forces. And when the reforms were popularized, the Chinese characters began a new round of natural change.
