Before the writing of Chinese characters evolved into regular script, the top of Chinese characters was not a mountain, but a horizontal mountain-shaped radical. Later, with the evolution of Chinese characters, it evolved into today's mountain characters. When regular script first evolved, the mountain inherited the form of seal script, evolved into frontier fortress mountain, and later evolved into the present mountain prefix.
The Evolution of Chinese Characters is a book that studies the evolution of Chinese characters. This book * * selects 500 commonly used Chinese characters (plus more than 660 loanwords and borrowed words mentioned in the definition * *), and each character lists five fonts in turn: Wen Tao, Oracle Bone Inscriptions, Jinwen, Xiaozhuan, Lishu and Regular Script (some of which have been simplified, plus simplified Chinese characters, * * * nine fonts) from 1200. For example, in ancient times, some consonants disappeared from Chinese. In addition, there are some obvious changes in tone. For a long time, Chinese characters have not had a standard phonetic notation tool, which is one of the important reasons for their natural pronunciation changes.
