1. Body language (body language). Language is often not independent of expression, posture and demeanor. People's understanding of language often relies on the assistance of these three. However, in a certain social environment, a body language information system composed of expressions, postures, and demeanor, and expressing meaning through body movements, can still communicate without language. For example, greetings include the Chinese bow, the Japanese bow (the degree and duration of the bow vary according to different status and status), the Indian hands together, the Western handshake, etc.

2. Expression language. It is the dissemination of information sent by people with no fixed meaning, such as various laughter, crying, sighing, moaning, shouting, etc. This is because human information communication is inseparable from the expression and transmission of emotions, and the transmission of emotions depends to a large extent on "how to say" rather than "what is said". As the saying goes, listen to the words. The same sentence expressed in different tones has completely different effects.

3. Art. This is an advanced level of nonverbal communication. Natural language can be classified as inferential symbols, while art (painting, architecture, music, dance, etc.) belongs to representational symbols. Representational symbols are non-linguistic symbols used to express emotional meanings that verbal symbols cannot express.

Some text symbols are easy to understand and operate, such as C language, which is relatively common and is a computer programming language. It has the characteristics of both high-level languages ??and assembly languages. For example, physical current symbols, current equipment symbols, chemical periodic table of elements, etc.

Nowadays, Mars characters are popular on the Internet. Only those who frequently use the Internet will understand. For example, "porridge" (like) is not only an Internet term, but also expresses the rising young fashion style in the trend of the times. At the same time, it also brings humor and fun to the high-paced urban life.
