"Kongbi" is a buzzword in Japanese network language, which comes from the abbreviations of "Kon" and "bi" in Japanese. It was originally used to describe the madness of anime fans and game fans, and then it gradually expanded to other fields and became a buzzword. Control ratio is very popular among Japanese young people and is often used to describe their love for a certain field. For example, a game fan may say that he is a "game control ratio", and an anime fan may say that he is a "secondary control ratio".

Controlling the ratio has now become an important part of Japanese youth culture. In Japan, all walks of life have their own corresponding control ratios, such as food control ratio, musical instrument control ratio, hand control ratio, face control ratio and so on. These control groups communicate with each other, share experiences and form their own social circles, which has become a unique cultural phenomenon in Japan.

Control ratio is not only a unique cultural phenomenon in Japan, but also has begun to spread widely around the world. Many control groups have established their own communities and forums on the Internet to exchange experiences and feelings with each other. Some Japanese animation, games and other cultural products also sell well overseas, attracting a large number of young people from Europe, America and Asia to join the fan control group. The appearance of comparison reflects the unique lifestyle and cultural characteristics of modern young people, and its development will also affect the development direction of Japanese culture in the future.
