Doudilu is a Chinese trademark "Dudilu" and an English trademark "Doudilu" registered by Dunhill (Hong Kong) Clothing Development Co., Ltd. in France. However, they did not use these trademarks when selling goods, but used a company name "Dunhill, France" similar to a famous brand, misleading consumers in the birthplace and origin of the brand. Moreover, European countries such as Britain and France have many similarities in history and tradition, and consumers who don't understand them will be confused. Taking Dunhill, France as the manufacturer of Dunhill, France, based on this confusion, consumers think that they are buying related products of well-known brands, and there is a purchase behavior against their true wishes, which makes consumers have a major misunderstanding in their purchase behavior.
