Popular culture plays an important role in the global cultural process. Hollywood in the United States has occupied a monopoly position in the global cultural market since the beginning of the 20th century, and it is constantly updating and developing. This enlightens us that the influence of a country's culture lies in the promotion and popularization of classic and traditional culture on the one hand and the cultivation of core values on the other; But at the same time, the international influence of pop culture is also a key. From popular culture, people can appreciate a nation's present reality and its imagination and creativity. From popular culture, people can feel the direct possibility of communication and dialogue between a society and other societies. The image of a country comes from both its high-end elite culture and popular culture regarded as "low-end". Cross-cultural understanding of elegant and profound culture is often more difficult for people of other cultures, while the vividness and directness of popular culture can often form a "healthy", "optimistic" and energetic impression. The success of Avatar is not only a matter of artistic expression, but also a global influence brought by the comprehensive combination of the ability to master and set the agenda, scientific and technological ability and artistic experience in the field of popular culture. Popular culture has three characteristics that are conducive to cross-cultural and cross-regional communication: First, there are few cultural barriers in form, few cultural discounts and easy to understand and be familiar with. With a wider and more convenient way of transmission. Second, popular culture often expresses values through emotional communication, which has more vivid and concrete communication effects. Third, popular culture can make people know the real life of a society and have more vivid communication feelings.

When people talk about the "going out" of China culture, they often think of China's profound traditional culture. The realistic popular culture is actually an indispensable part of "Made in China", and its positive aspects can also be accepted and loved by the world. To create a "charming China", it is necessary to attract people who are interested in China's traditional culture as well as China's popular culture. Cultural China should include not only traditional culture China and elite culture China, but also popular culture China. Of course, we should also pay attention to and be alert to the negativity and vulgarization of popular culture. Now it seems that there are still obstacles and troubles in the direct spread of China's popular culture to western developed countries. On the one hand, the West has traditionally had a sense of distance from the cultures of developing countries and emerging countries; on the other hand, the western popular culture is highly mature, and China's cultural products are hard to compete with. However, for regions and societies with the same or similar culture as China, and for emerging countries and developing countries facing similar development problems and living environments, the charm of China's current pop culture cannot be ignored. We have always been very concerned about the spread of overseas culture in the West. In fact, we should pay more attention to the communication effect, and pay attention to the communication between regions and societies connected by culture and developing countries and emerging countries. Only in this way can we have a better communication effect and function.
