Monograph means that a Chinese character has only one shape, not two or more shapes. Most of these characters are simple hieroglyphs and signifiers. Because these characters evolved from pictures, each character is a whole, so it should be regarded as a letter combination symbol, because it cannot be divided into two or more parts.

There are several combinations that form single letters and discrete relationships: namely, strokes have a certain distance and do not touch each other, such as Ba, Zi, Chuan, Xin and Liu.

Connection relationship: that is, strokes are connected with each other, such as people, workers, people, people, people, people, people, people, people, people, people, people, people, people, people, people.
