(1) Oral advertising Oral advertising, also known as hawking, is the most primitive and simple form of advertising and is still the most common form of advertising. According to legend, Jiang Taigong, who assisted King Wen of Zhou to establish his hegemony, lived in seclusion in the market and engaged in butchering when he was not appointed. In the shop, he "drums, knife and shouts" and shouts to attract customers. The slave markets and livestock markets in ancient Greece also used rhythmic shouting for advertising. Oral advertising in the form of poetry also appeared. In ancient China, hawking advertisements were also very developed. Vendors often used different tones when hawking, so that people could tell what the vendors were selling at a glance. Nowadays, the cries with special charm that are occasionally heard in the streets and alleys, such as the Yangzhou dialect of "grinding scissors and sharpening kitchen knives", are probably still a relic of ancient times. (2) Physical advertising Physical advertising is also an ancient form of advertising, which relies on displaying product styles to attract customers. In order to sell goods, merchants put the goods out for buyers to watch and choose. There is a description of this form of advertising in the "Book of Songs": "The hooligans hold cloth and trade silk." This illustrates the form of barter-for-barrel display of goods at that time. Physical advertising is still the most basic form of commercial advertising, but the level of display design is much higher than in the past.
