Dried plums suddenly became popular abroad. Is this a cultural output?

Cultural output refers to a country's indoctrination of other countries' cultures. The initial stage of cultural output is a kind of cultural identity. For example, the Marvel comic culture in the United States has an influence on the culture of China. We all think that American movies are excellent productions, so many people pursue American Marvel comic culture, which contains American unique heroic culture. When people are exposed to his films, they are also exposed to his culture, which is an intangible output of culture. In politics and other aspects, the recognition of American culture is in a general state of mind in our society, so the export of American culture to China is very successful, just as many people are willing to immigrate to the United States now. The final result of cultural output is quite horrible. When a nation's culture is assimilated by other nations, then this nation loses its unique particularity and becomes a member of other nations. The main cultural exports are divided into two categories, the first category is urban construction and infrastructure construction, and the second category is closer to people's lives, such as Spring Festival, Chinese food, Kung Fu and Peking Opera. At present, the main force of publicity seems to be urban construction and infrastructure, but apart from Chinese food and kung fu, ordinary foreigners seem unable to arouse their interest, so foreigners' impression of China is quite different from the actual situation. In addition, many foreigners have never actually been to China, and they have never been exposed to the lifestyle and culture of China. Like the French grandmothers I met in America, many Europeans like to travel to Japan. Although the Japanese only eat tempura, beef rice, Lamian Noodles, sushi and barbecue, they know how to package and export to other countries, just like animation, so they have been exposed to many countries in Europe and America. There are many life scenes in the animation, so they are easier to understand. While I was in America, my roommate was watching Naruto. He said that he liked the animation very much. I think from this aspect, we can also see how much influence good cultural output has on ordinary people.
