The origin of the logo can be traced back to the totem of ancient times. At that time, each clan and tribe chose an animal or natural object that they thought had a special mysterious relationship with themselves as a special mark of their clan or tribe (that is, totem). For example, the Nvwa clan took snakes as totems, Xia Yu's ancestors took yellow bears as totems, and others took the sun, moon and crow as totems. At first, people carved totems on living caves and working tools. Later, totems became national flags and Emblems as symbols of war and sacrifice. After the emergence of the country, it has evolved into the national flag and emblem.

　　古代人们在生产劳动和社会生活中，为方便联系、标示意义、区别事物的种类特征和归属，不断创造和广泛使用各种类型的标记，如路标、村标、碑碣、印信纹章等。广义上说，这些都是标志。在古埃及的墓穴中曾发现带有标志图案的器皿多半是制造者的标志和姓名，后来变化成图案。在古希腊，标志已广泛使用.在罗马和庞贝以及巴勒斯坦的古代建筑物上都曾发现刻有石匠专用的标志，如新月车轮、葡萄叶以及类似的简单图案。自有作坊店铺，就伴有招牌、幌子等标志。在唐代制造的纸张内已有暗纹标志。到宋代,商标的使用已相当普遍。如当时济南专造细针的刘家针铺，就在商品包装上印有兔的图形和"认门前白兔儿为记"字样的商标。欧洲中世纪士兵所戴的盔甲，头盖上都有辨别归属的隐形标记，贵族家族也都有家族的徽记。

　　In production, labor and social life, ancient people created and widely used various types of markers, such as road signs, village signs, stele pillars, seal badges and so on, for the convenience of contacting, signifying meanings and distinguishing the characteristics and attribution of things. Broadly speaking, these are signs. In the tombs of ancient Egypt, it was found that most of the vessels with logo patterns were the makers'logos and names, which later changed into patterns. In ancient Greece, signs have been widely used. In ancient buildings in Rome and Pompeii, as well as in Palestine, masonry-specific signs such as crescent wheels, grape leaves and similar simple patterns have been found. China's own workshop shops are accompanied by signs, masks and other symbols. The paper made in the Tang Dynasty has dark markings. By the Song Dynasty, the use of trademarks was quite common. For example, Liu Jia Needle Shop, which specializes in fine needles in Jinan at that time, printed the image of rabbit on the commodity package and the trademark of "recognizing the white rabbit in front of the door as a mark". The armor worn by soldiers in medieval Europe bears invisible signs of belonging on their heads and family emblems on noble families.

　　到本世纪，公共标志、国际化标志开始在世界普及。随着社会经济、政治、科技、文化的飞跃发展，到现在，经过精心设计从而具有高度实用性和艺术性的标志，已被广泛应用于社会一切领域，对人类社会性的发展与进步发挥着巨大作用和影响。一门新兴的科学--"符号标志学"应运而生已是历史必然。

　　By this century, public signs and international symbols have become popular in the world. With the rapid development of social economy, politics, science and technology, and culture, the highly practical and artistic symbols which have been carefully designed have been widely used in all fields of society, playing a huge role and influence on the development and progress of human sociality. The emergence of a new science, symbology, is a historical necessity.
