Logo, also known as word logo, is a sign that people use to express the characteristics of something in their lives. It takes simple, obvious and easily recognizable images, graphics or text symbols as its intuitive language. Besides what it represents and replaces, it also has the functions of expressing meaning, emotion and indicating actions. The symbols interpreted by modern Chinese dictionaries are symbols that represent characteristics.

The origin of this symbol can be traced back to the ancient "totem". At that time, every clan and tribe chose an animal or natural image that they thought had a special mysterious relationship with themselves as a special symbol (totem) of their clan or tribe. For example, Nuwa people take snakes as their totems, Yu Xia's ancestors take yellow bears as their totems, and others take crows from the sun and the moon as their totems.

At first, people carved totems on caves and labor tools where they lived, and later they became national flags and badges as symbols of war and sacrifice. After the birth of the country, it evolved into a national flag and national emblem.
