In modern society, the behavior of selling dog meat by hanging sheep's head still exists. In order to maximize profits, some businesses will cheat consumers by various means. For example, in the food industry, some merchants will add some unhealthy ingredients to food to improve the taste and color of food, but these ingredients are harmful to human health. There are also some businesses who exaggerate and make false propaganda on the packaging of goods to attract consumers' attention, but in fact, the quality of goods is not as good as advertised.

Hanging sheep's head to sell dog meat is not only a deception to consumers, but also a damage to the reputation of the merchants themselves. If a merchant often cheats consumers in this way, then consumers will lose trust in the merchant, and eventually the business of the merchant will get worse and worse. Therefore, merchants should abide by the principle of honest management, constantly improve product quality and enhance consumers' trust.
