What are the concepts of ancient Chinese characters and modern Chinese characters? How are they different from ancient and modern figures? Please answer more specifically.

There are many topics, let's start with ancient and modern figures.

Ancient and modern figures

From the general development trend, the physical structure of Chinese characters is from single word to combination; The meaning of this word is returned by Bo. At first, a word had several meanings at the same time, and later a new combination word was created to share some of the meanings expressed by the original word. This relationship between "original words" and "new words" constitutes the relationship between "ancient" and "present" Ancient Chinese characters are also called "initial Chinese characters" in philology, and modern Chinese characters are also called "post-pictophonetic characters" or "post-Chinese characters"

It can be seen that the original meaning of "Mo" is "Twilight". However, "Mo" also has other meaning. Later generations added "sun" to "Mo" and created a word "sunset" to share the meaning of "people and ghosts" expressed by "Mo". "Mo" appears in the front and "Twilight" appears in the back, so "Mo" and "Twilight" are also ancient and modern characters (meaning that structural characters become pictophonetic characters).

The above is for reference only!

Please correct me if there is anything wrong!
