A country's flag is not just a piece of cloth with various colors and patterns, but also a reflection of the country's culture, history and political system. The design of a country's national flag should conform to the national conditions, national characteristics and the spirit of the times. At the same time, it should also deepen the patriotism education of the people through various forms and methods, so that the people can know their own flag and understand the meaning of the flag.

Trademark is an extremely important commercial symbol in the modern market economy. It is the image representative of the corporate brand and a symbol of business reputation. The choice and design of trademarks can directly affect the company's market positioning, brand image and sales performance. Therefore, when designing a trademark, an enterprise should pay attention to the uniqueness and innovation of the trademark. At the same time, it is necessary to consider the combination of the trademark and the company's publicity to form an integrated image of the brand and the enterprise and improve market competitiveness.
