Why do some people think that geisha who are engaged in singing and dancing only existed in ancient Japan?

Geisha was a profession in ancient China, Japanese and other countries and regions. However, the influence of geisha is greater in Japan than in other places, and there are also many literary works about geisha in Japanese history, such as the novel "The Map of Geisha". Therefore, some people may think that the geisha profession is unique to Japan.

However, in ancient China, India, ancient Greece and other places, there was also the profession of geisha. For example, in ancient China, geisha usually played musical instruments, sang and danced in palaces, temples and rich people's homes, and might also take part in performances. In ancient Greece, geisha usually performed art in theaters, temples and banquets, and also worked in places where they sold art. Therefore, the profession of geisha is not unique to Japan, but existed all over the ancient world.
