Why do some people think that geisha, a profession of song and dance, only existed in ancient Japan?

The geisha profession existed in ancient China, Japan and other countries and regions. However, the geisha profession was more influential in Japan than elsewhere, and there have been many literary works about geisha in Japanese history, such as the novel "Geisha Pictures". Therefore, some people may think that the profession of geisha is unique to Japan.

However, geishas were also practiced in ancient China, India, and ancient Greece. For example, in ancient China, geishas usually played musical instruments, sang and danced in courts, temples and the homes of the rich, and might also take part in performances. In Ancient Greece, geishas usually performed their art in theaters, temples, and banquets, and might also work in venues where they sold their art. Therefore, the profession of geisha was not unique to Japan, but was found throughout the world in ancient times.
