In is a very common word among Korean idol fans, which translates into entering, matching or consistent in Chinese. In Korean entertainment circles, in is usually used to describe the state of singing or emotional singing. For example, fans who support a Korean singer or actor will issue the slogan "I am here" to express their support and love for the star.

Korean circle in and other popular words such as "geili" and "magic game" are all translated from Chinese characters belonging to Korean. These buzzwords are usually used by young people on online communication platforms. They didn't appear for a long time, but they can be seen on every social media platform.

Judging from the scope involved, the Korean wave circle undoubtedly contains many things related to Korean wave entertainment. With the gradual popularity of Korean music, movies, TV series and games, more and more people will learn more about Korean circle culture and have a strong interest in it. At the same time, with the popularity of social media and mobile devices, people's social ways are constantly changing. I believe that more and more people will use the word "Korean circle in" and incorporate it into a wider network of social activities.
