2. The origin of the logo can be traced back to the totems of ancient times. At that time, each clan and tribe chose an animal or natural object that it believed had a special mysterious relationship with itself as a special mark of the clan or tribe (called a totem). For example, the Nuwa clan uses snakes as their totems, Xia Yu's ancestors use the yellow bear as their totems, and some use the sun, moon, and crow as their totems. At first, people carved totems on the caves where they lived and on working tools. Later, they became symbols of war and sacrifice, and became clan flags and emblems. After the country was born, it evolved into the national flag and national emblem.

Most of the vessels with logo patterns found in ancient Egyptian tombs were the maker's logo and name, which were later changed into patterns. In ancient Greece, signs were widely used. Stonemason's symbols such as crescent wheels, grape leaves, and similar simple designs have been found carved on ancient buildings in Rome and Pompeii, as well as in Palestine. China's own workshops and shops are accompanied by signs, banners and other signs. Paper produced in the Tang Dynasty already had dark markings in it. By the Song Dynasty, the use of trademarks had become quite common. For example, the Liujia Needle Shop in Jinan, which specialized in manufacturing fine needles at that time, printed the image of a rabbit on its product packaging and identified the white rabbit in front of the door as its trademark. The armor worn by European medieval soldiers had invisible marks on their head coverings to identify their affiliations, and noble families also had family emblems.
