1. Visualization and intuitive recognition: The glyphs of hieroglyphs often have intuitive similarities with the shapes of the things or concepts they represent, and concepts are expressed through images, which has strong visual expressive force. For example, the word "sun" is shaped like the sun, and the word "mountain" is shaped like a mountain.

2. Antiquity and plasticity: Ideographic characters are one of the early forms in the development history of Chinese characters with a long history. In the process of evolution, hieroglyphics can be simplified, processed or combined, creating new Chinese characters and expanding vocabulary.

3. Simple and easy to read: Because hieroglyphics represent the shape and characteristics of things, their glyphs are often simple and easy to identify and remember. This is also a factor that they were widely used in ancient times.
