Hanfu is a traditional national costume in China with a long history and cultural background. However, there are indeed many people who have limited or insufficient understanding of Hanfu. There may be the following reasons:

Interruption of cultural inheritance: In the historical process of China, it experienced many political, social and cultural changes, including wars, revolutions and the influence of foreign cultures, which led to the interruption and partial loss of traditional culture. This also affects the understanding and inheritance of Hanfu.

Lack of education system: in some education systems, the education and publicity of traditional culture may be relatively insufficient, and more attention is paid to modernization and internationalization. This makes some people not know enough about Hanfu in school education.

Influence of media and popular culture: In modern society, media and popular culture have great influence on people's values and aesthetic concepts. Some popular culture propaganda and media reports may pay more attention to modern fashion and international trends, but less attention to traditional culture and Hanfu.

Regional differences: China has a vast territory, and different regions have different cultural traditions and clothing styles. Therefore, some areas may have a deeper understanding and inheritance of Hanfu, and some areas may be relatively less.

Nevertheless, in recent years, more and more people have begun to pay attention to and love traditional culture, including Hanfu. In social media and various cultural activities, Hanfu appears more and more frequently, which also attracts more people's attention and understanding.
