All is like everything in this world. Any substance consists of molecules. The Chinese language consists of characters.
An atom consists of an electron, a proton and a neutron. A Chinese character consists of radicals and components.
There are 118 officially registered chemical elements in the periodic table and 214 generally recognized radicals in the Chinese language.
Each chemist should know the periodic table, each Chinese learner should know how to decompose a Chinese character into radicals and components. The Chinese radicals and components added one to another produce new characters. To understand this process one should know the decomposition of the Chinese characters.
